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).

This might be pretty awful, but at least it is a complete and non-flaky
solution.
**Only when using the rollingupgrade test** (which implies a throwaway
satellite and also a PostgreSQL backend), create a trigger on the nodes
table which forces last_net to be equal to last_ip_port always.

This test involves a satellite with dev defaults (DistinctIP=no) being
upgraded past commit 2522ff09b6, which
means we need to run the dev-defaults-satellite-upgrade migration SQL
to avoid getting DistinctIP=yes behavior (which breaks the tests).

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.

we have two more fields in the database (noise_proto and
noise_public_key) that now need to go into pb.NodeAddress when
returning AddressedOrderLimits.
the only real complication is making sure type conversions between
database types and NodeURLs and so on don't lose this new
pb.NodeAddress field (NoiseInfo). otherwise this is a relatively
straightforward commit

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
version update email (no condition is true), the value would be set to
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.

SetNodeContained() will change the contained flag in the nodes table,
which will affect whether nodes are selected for new uploads. This flag
_should_ correlate with whether or not a given node has any entries in
the reverification queue. However, the reverification queue is intended
to be 'safely partitionable' from the nodes table, so we can't enforce
that characteristic transactionally. But this is ok; there are no dire
consequences if they are out of sync.
We will be adding a chore that updates the contained flag based on the
contents of the reverification queue periodically, if something fails
to set it directly when appropriate.

inconsistency
The original design had a flaw which can potentially cause discrepancy
for nodes reputation status between reputations table and nodes table.
In the event of a failure(network issue, db failure, satellite failure, etc.)
happens between update to reputations table and update to nodes table, data
can be out of sync.
This PR tries to fix above issue by passing through node's reputation from
the beginning of an audit/repair(this data is from nodes table) to the next
update in reputation service. If the updated reputation status from the service
is different from the existing node status, the service will try to update nodes
table. In the case of a failure, the service will be able to try update nodes
table again since it can see the discrepancy of the data. This will allow
both tables to be in-sync eventually.

We had a bug in the stray nodes chore where nodes who had not been seen
in several months were not being DQd. We figured out that this was
happening because we were using two queries: The first to grab
nodes where last_contact_success < some cutoff, the second to DQ them
unless last_contact_success == '0001-01-01 00:00:00+00'. The problem
is that if all of the nodes returned from the first query had
last_contact_success of '0001-01-01 00:00:00+00', we would pass them to
the second query which would not DQ them. This would result in the stray
nodes DQ loop ending since we found a number of nodes to DQ less than the
limit.
The fix: add the "WHERE last_contact_success != '0001-01-01
00:00:00+00'::timestamptz" to the selection query.

Until now, whenever audits were recorded we would try to delete
the node from containment just in case it exists. Since we now
want to treat segment repair downloads as audits, this would
erroneously remove nodes from containment, as repair does not go
through a Reverify step. With this changeset, (Batch)UpdateStats
will not remove nodes from containment. The Reverify method will
remove all necessary nodes from containment.

Currently we were duplicating code for AS OF SYSTEM TIME in several
places. This replaces the code with using a method on
dbutil.Implementation.
As a consequence it's more useful to use a shorter name for
implementation - 'impl' should be sufficiently clear in the context.
Similarly, using AsOfSystemInterval and AsOfSystemTime to distinguish
between the two modes is useful and slightly shorter without causing
confusion.

errs.Class should not contain "error" in the name, since that causes a

Whereas something like:
ERROR nodestats service: satellitedbs: nodestatsdb: no rows

When nodes check in for the very first time, if the satellite can't ping
