as GetParticipatingNodes and GetNodes, respectively.
We now want these functions to include offline and suspended nodes as
well, so that we can force immediate repair when pieces are out of
placement or in excluded countries. With that change, the old names no
longer made sense.

As I learned, the `Include` supposed to communicate that some internal change also "included" to the filters during the check -> filters might be stateful.
But it's not the case any more after 552242387, where we removed the only one stateful filter.

Once uppon a time, at the dawn of the implementation of Storj, when all the nodes are read from the database directly, every time.
After a while -- due to performance reasons -- it has been changed for upload and download: where all the nodes are read for a short period of time, and used from memory.
This is the version which was improved recently to support advanced node selections using placement.
But stil we have an old configuration value `service.config.NodeSelectionCache.Disabled`, and the db based implementation: `service.FindStorageNodesWithPreferences(ctx, req, &service.config.Node)`.
For safety, we need to remove this option, to make sure that we use the cache, which has the advanced features.
This patch was supposed to be a very small one (just removing a method and a config: https://review.dev.storj.io/c/storj/storj/+/11074/1/satellite/overlay/service.go), but it turned out that we need to update a lot of unit tests.
These unit tests used the old implementation (which is not used in production any more).
The tests which used both implementation are just updated to use only the new one
The tests which used only the old implementation are refactored (but keeping the test cases).

This patch is a oneliner: rangedloop checker should check the subnets only if it's not turned off with placement annotation.
(see in satellite/repair/checker/observer.go).
But I didn't find any unit test to cover that part, so I had to write one, and I prefered to write it as a unit test not an integration test, which requires a mock repair queue (observer_unit_test.go mock.go).
Because it's small change, I also included a small change: creating a elper method to check if AutoExcludeSubnet annotation is defined

This patch makes it easier to configure existing placement rules only with string.
1. placement(n) rule can be used to reuse earlier definitions
2 .&& can be used in addition to all(n1,n2)

There are cases when we would like to override the default placement=0 rule.
For example when we would like to exclude tagged nodes from the selection (by default).
Therefore we couldn't use a shortcut any more, we should always check the placement rules, even if we use placement=0.

Current node selection logic (in case of using SelectBySubnet):
1. selects one subnet randomly
2. selects one node randomly from the subnet
3. applies the placement NodeFilters to the node and ignore it, if doesn't match
This logic is wrong:
1. Imagine that we have a subnet with two DE and one GB nodes.
2. We would like to select DE nodes
2. In case of GB node is selected (randomly) in step2, step3 will ignore the subnet, even if there are good (DE) nodes in there.

stats/size/count is not used by any production code, and it's not required, as we can assert the state with other checks.

Currently, we have issue were while counting unhealthy pieces we are

placement. This can cause unnecessary repair.

placement.AllowedCountry is the old way to specify placement, with the new approach we can use a more generic (dynamic method), which can check full node information instead of just the country code.
The 90% of this patch is just search and replace:
* we need to use NodeFilters instead of placement.AllowedCountry
* which means, we need an initialized PlacementRules available everywhere
* which means we need to configure the placement rules
The remaining 10% is the placement.go, where we introduced a new type of configuration (lightweight expression language) to define any kind of placement without code change.

ReliabilityCache will be now using refactored overlay Reliable method.
This method will provide more info about nodes (e.g. country code) and
with this we are able to add two dedicated methods to classify pieces:
* OutOfPlacementPieces
* PiecesNodesLastNetsInOrder
With those new method we will fix issue where offline but reliable node
won't be checked for clumped pieces and off placement pieces.

Currently we are using Reliable to get missing pieces for repair
checker. The issue is that now checker is looking at more things than
just missing pieces (clumped/off, placement pieces) and using only node
ID is not enough. We have issue where we are skipping offline nodes from
clumped and off placement pieces check.
Reliable was refactored to get data (e.g. country, lastNet) about all
reliable nodes. List is split into online and offline. This data will be
cached for quick use by repair checker. It will be also possible to
check nodes metadata like country code or lastNet.
We are also slowly moving `RepairExcludedCountryCodes` config from
overlay to repair which makes more sens for it.
This this first part of changes.

is looking at more things than just missing pieces (clumped/off
placement pieces).
KnownReliable was refactored to get data (e.g. country, lastNet) about
all reliable nodes from provided list. List is split into online and

checks: missing pieces, clumped pieces, out of placement pieces.

We were using the UploadSelectionCache previously, which does _not_ have
all nodes, or even all online nodes, in it. So all nodes with less than
MinimumVersion, or with less than MinimumDiskSpace, or nodes suspended
for unknown audit errors, or nodes that have started graceful exit, were
all missing, and ended up having empty last_nets. Even with all that,
I'm kind of surprised how many nodes this involved, but using the upload
selection cache was definitely wrong.
This change uses the download selection cache instead, which excludes
nodes only when they are disqualified, gracefully exited (completely),
or offline.

The query for GetNodesNetworkInOrder is causing far too much load on the

We avoid putting more than one piece of a segment on the same /24
network (or /64 for ipv6). However, it is possible for multiple pieces
of the same segment to move to the same network over time. Nodes can
change addresses, or segments could be uploaded with dev settings, etc.
We will call such pieces "clumped", as they are clumped into the same
net, and are much more likely to be lost or preserved together.
This change teaches the repair checker to recognize segments which have
clumped pieces, and put them in the repair queue. It also teaches the
repair worker to repair such segments (treating clumped pieces as
"retrievable but unhealthy"; i.e., they will be replaced on new nodes if
possible).

We have a specific issue that a user uploaded a file to a bucket
geo-fenced to EU and one of the pieces appeared to be on a node in the
US. The country code of this node is set to SE (Sweden) in the satellite
DB. It turns out that some time ago MaxMind changed the country code of
this node's IP from Sweden to US, but this change hasn't been reflected
in the satellite's database.
So far the satellite updates the country code of a node only if its IP
changes. It was assumed that if the IP does not change, its country code
shouldn't change too. This turned to be a wrong assumption.
With this change, the satellite will look up the MaxMindDB on every
check-in to see if the country code of the node's IP has changed.

This test involves a satellite with dev defaults (DistinctIP=no) being

Up to now, we have been implementing the DistinctIP preference with code
in two places:
1. On check-in, the last_net is determined by taking the /24 or /64
(in ResolveIPAndNetwork()) and we store it with the node record.
2. On node selection, a preference parameter defines whether to return
results that are distinct on last_net.
It can be observed that we have never yet had the need to switch from
DistinctIP to !DistinctIP, or from !DistinctIP to DistinctIP, on the
same satellite, and we will probably never need to do so in an automated
way. It can also be observed that this arrangement makes tests more
complicated, because we often have to arrange for test nodes to have IP
addresses in different /24 networks (a particular pain on macOS).
Those two considerations, plus some pending work on the repair framework
that will make repair take last_net into consideration, motivate this
change.
With this change, in the #2 place, we will _always_ return results that
are distinct on last_net. We implement the DistinctIP preference, then,
by making the #1 place (ResolveIPAndNetwork()) more flexible. When
DistinctIP is enabled, last_net will be calculated as it was before. But
when DistinctIP is _off_, last_net can be the same as address (IP and
port). That will effectively implement !DistinctIP because every
record will have a distinct last_net already.
As a side effect, this flexibility will allow us to change the rules
about last_net construction arbitrarily. We can do tests where last_net
is set to the source IP, or to a /30 prefix, or a /16 prefix, etc., and
be able to exercise the production logic without requiring a virtual
network bridge.
This change should be safe to make without any migration code, because
all known production satellite deployments use DistinctIP, and the
associated last_net values will not change for them. They will only
change for satellites with !DistinctIP, which are mostly test
deployments that can be recreated trivially. For those satellites which
are both permanent and !DistinctIP, node selection will suddenly start
acting as though DistinctIP is enabled, until the operator runs a single
SQL update "UPDATE nodes SET last_net = last_ip_port". That can be done
either before or after deploying software with this change.
I also assert that this will not hurt performance for production
deployments. It's true that adding the distinct requirement to node
selection makes things a little slower, but the distinct requirement is
already present for all production deployments, and they will see no
change.

We will be needing an infrequent chore to check which nodes are in the
reverify queue and synchronize that set with the 'contained' field in
the nodes db, since it is easily possible for them to get out of sync.
(We can't require that the reverification queue table be in the same
database as the nodes table, so maintaining consistency with SQL
transactions is out. Plus, even if they were in the same database, using
such SQL transactions to maintain consistency would be slow and
unwieldy.)
This commit adds a method to the overlay allowing the caller to set the
contained status of all nodes in the nodes table at once. This is valid
because our definition of "contained" now depends solely on whether a
node appears at least once in the reverification queue. Only rows whose
contained field does not match the expectation will be updated; the
contained timestamp will not be updated for a node which is supposed to
be contained and was already contained.

The CASE expression used to determine which value to set
last_software_update_email to did not have an ELSE clause. Therefore,
when the node is both below the minimum version and did not receive a

NULL.
Additionally, replace `time.Now()` with `timestamp` in the check to
determine if the email cooldown has passed.

`overlay.(*Service).UpdateReputation()` takes a "reputationChanges"
parameter, a slice of node events indicating whether we think the node's
disqualification or suspension status is changing. This is necessary so
that the overlay service can notify the nodeevents DB about these
changes.
In several cases, however, this list of events is not constructed
correctly, because of missing information about the previous state.
In most cases, this is because the node was offline, and the order limit
creation functions (which usually obtain and return the prior reputation
status) ignored that node.
This change makes it so that all callers to
`overlay.(*Service).UpdateReputation()` can be expected to provide a
correct list of change events (as correct as feasible, given that we
can't lock the node's information in the database during the entire
operation).
It ended up that there was only one caller we needed to worry about, and
that was reputation.(*Service).ApplyAudit(). So the bulk of this change
is teaching that function how to recognize when the prior reputation
status was not filled in, and fill it in.
