This PR implements reputation store and replace overlay in audit service
to use such store for storing node's audit stats.
In order to keep the changeset smaller, most of the changes in this PR is for copying audit logic in overlay to
reputation package. In a following PR, the duplicating code will be
removed from overlay.

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.

When audits are being recorded, we automatically add some SQL to remove
the node from the pending audits table in case it exists. They are
removed from pending audits even if the node was offline for the audit.
This is not the correct behavior.
Add statement to record audit results in reverify tests to ensure no
more false positives.

errs.Class should not contain "error" in the name, since that causes a
lot of stutter in the error logs. As an example a log line could end up
looking like:
ERROR node stats service error: satellitedbs error: node stats database error: no rows
Whereas something like:
ERROR nodestats service: satellitedbs: nodestatsdb: no rows
Would contain all the necessary information without the stutter.

When nodes check in for the very first time, if the satellite can't ping
them back, they are inserted into the nodes table with
last_contact_success of '0001-01-01 00:00:00+00'. If the stray nodes
chore runs before the node can fix their problem, they are DQd.
Solution: when DQing stray nodes, dont DQ where last_contact_success =
'0001-01-01 00:00:00+00'::timestamptz

This change introduces a new config flag,
--overlay.audit-history.offline-suspension-enabled,
to toggle suspending nodes for offline audits.
If the flag is set to true, nodes will be suspended if they meet the
requirements.
If the flag is false, nodes will not be suspended. If they are already
suspended and/or under review, these will be cleared.

Previously we would select a limited number of nodes for DQ in a
CTE and run the update on that set in a single transaction. This
could lead to locking on the table, so instead we select and update
in separate transactions.

We would like to log Node IDs and last contact successes of nodes DQd
in this manner. We would also like to avoid returning an unbounded list
of items from the db. Therefore we change the query to select a limited
number of nodes that meet the DQ conditions and iterate until 0 rows are
returned. Each column of the query is already indexed.

Full scope:
private/testplanet,satellite/{overlay,satellitedb}
Description:
In most cases, downtime tracking with audits will eventually lead
to DQ for nodes who are unresponsive. However, if a stray node has no
pieces, it will not be audited and will thus never be disqualified.
This chore will check for nodes who have not successfully been contacted
in some set time and DQ them.
There are some new flags for toggling DQ of stray nodes and the timeframes
for running the chore and how long nodes can go without contact.

Query nodes table using AS OF SYSTEM TIME '-10s' (by default) when on CRDB to alleviate contention on the nodes table and minimize CRDB retries.

With the new overlay.AuditOutcome type for offline audits, the
IsUp field is redundant. If AuditOutcome != AuditOffline, then
the node is online.
In addition to removing the field itself, other changes needed
to be made regarding the relationship between 'uptime' and 'audits'.
Previously, uptime and audit outcome were completely separated. For
example, it was possible to update a node's stats to give it a
successful/failed/unknown audit while simultaneously indicating that
the node was offline by setting IsUp to false. This is no longer possible
under this changeset. Some test which did this have been changed slightly
in order to pass.
Also add new benchmarks for UpdateStats and BatchUpdateStats with different
audit outcomes.

- Remove flag for switching off offline audit reporting.
- Change the overlay method used from UpdateUptime to BatchUpdateStats, as this
is where the new online scoring is done.
- Add a new overlay.AuditOutcome type: AuditOffline. Since we now use the same
method to record offline audits as success, failure, and unknown, we need to
distinguish offline audits from the rest.

Previously if a node did not have audit history data for each of the
windows over the tracking period, we would give them the benefit of
the doubt and set their score to 1. This was to prevent nodes from
being suspended right out the gate. We need a minimum amount of data
to evaluate them.
However, a node who is actually failing at being online will have no
idea until they have received enough audits and we suspend them.
Instead, we will always use their real score, but use a flag to determine
whether they are eligible for suspension/dq.

Additionally, this PR changes NewNodeFraction devDefault and testplanet config from 0.05 to 1.
This is because many tests relied on selecting nodes that were reputable based on audit and uptime
counts of 0, in effect, selecting new nodes as reputable ones.
However, since reputation is now indicated by a vetted_at db field that is explicitly set
rather than implied by audit and uptime counts, it would be more complicated to try to
update all of the nodes' reputations before selecting nodes for tests.
Now we just allow all test nodes to be new if needed.

Add online score used for the new audit history offline tracking system
to the nodes table. This allows us easy access to the node's online

When a node's audit history "online score" passes below a configured
threshold, the node goes into "offline suspension" mode and begins a
review period, where the operator is given an opportunity to bring their
node back online.
After the review period passes, offline suspension is turned off for the
node.
In the future, if a node still has a bad online score at the end of the
review period, it will be disqualified. This is disabled right now.
In the future, if a node is in offline suspension, it will be treated as
"unhealthy". Right now, there are no consequences for being in offline
suspension.
Minor changes:
* Moves AuditHistoryConfig out of UpdateStats/BatchUpdateStats args and
into UpdateRequest.
* Adds "now" argument to UpdateStats/BatchUpdateStats args for easy
testing.
* Changes formatting strings inside buildUpdateStatement to use specific

What:
Use the github.com/jackc/pgx postgresql driver in place of
github.com/lib/pq.
Why:
github.com/lib/pq has some problems with error handling and context
cancellations (i.e. it might even issue queries or DML statements more
than once! see https://github.com/lib/pq/issues/939). The
github.com/jackx/pgx library appears not to have these problems, and
also appears to be better engineered and implemented (in particular, it
doesn't use "exceptions by panic"). It should also give us some
performance improvements in some cases, and even more so if we can use
it directly instead of going through the database/sql layer.

What: As soon as a node passes the vetting criteria (total_audit_count and total_uptime_count
are greater than the configured thresholds), we set vetted_at to the current timestamp.
Why: We may want to use this timestamp in future development to select new vs vetted nodes.
It also allows flexibility in node vetting experiments and allows for better metrics around
vetting times.
Please describe the tests: satellitedb_test: TestUpdateStats and TestBatchUpdateStats make sure vetted_at is set appropriately
Please describe the performance impact: This change does add extra logic to BatchUpdateStats and UpdateStats and
commits another variable to the db (vetted_at), but this should be negligible.

Sometimes nodes who have gracefully exited will still be holding pieces
according to the satellite. This has some unintended side effects
currently, such as nodes getting disqualified after having successfully
exited.

finished graceful exit (audit/reporter_test.go TestGracefullyExitedNotUpdated)

Make sure that suspended nodes are treated appropriately by the overlay
cache. This means we should expect the following behavior:
* suspended nodes (vetted or not) should not be selected for uploading
new segments
* suspended nodes should be treated by the checker and repairer as
"unhealthy", and should be removed upon successful repair
This commit also removes unused overlay functionality.
Fixes a bug with commit 8b72181a1f where
the audit reporter was automatically suspending nodes regardless of
audit outcome (see test added).
Tests:
* updates repair tests to ensure that a suspended node is treated as
unhealthy and will be removed from the pointer on successful repair
* updates overlay tests for KnownUnreliableOrOffline and KnownReliable
to expect suspended nodes to be considered "unreliable"
* adds satellitedb test that ensures overlay.SelectStorageNodes and
overlay.SelectNewStorageNodes do not include suspended nodes
* adds audit reporter test to ensure that different audit outcomes
result in the correct suspended/disqualified states

* when unknown audit reputation goes above the DQ threshold, remove node
from suspension.
* record unknown audits from audit reporter.
* add basic tests around unknown audits and suspension.

My understanding is that the nodes table has the following fields:
- `address` field which can be a hostname or an IP
- `last_net` field that is the /24 subnet of the IP resolved from the address
This PR does the following:
1) add back the `last_ip` field to the nodes table
2) for uplink operations remove the calls that the satellite makes to `lookupNodeAddress` (which makes the DNS calls to resolve the IP from the hostname) and instead use the data stored in the nodes table `last_ip` field. This means that the IP that the satellite sends to the uplink for the storage nodes could be approx 1 hr stale. In the short term this is fine, next we will be adding changes so that the storage node pushes any IP changes to the satellite in real time.
3) use the address field for repair and audit since we want them to still make DNS calls to confirm the IP is up to date
4) try to reduce confusion about hostname, ip, subnet, and address in the code base

Backstory: I needed a better way to pass around information about the
underlying driver and implementation to all the various db-using things
in satellitedb (at least until some new "cockroach driver" support makes
it to DBX). After hitting a few dead ends, I decided I wanted to have a
type that could act like a *dbx.DB but which would also carry
information about the implementation, etc. Then I could pass around that
type to all the things in satellitedb that previously wanted *dbx.DB.
But then I realized that *satellitedb.DB was, essentially, exactly that
already.
One thing that might have kept *satellitedb.DB from being directly
usable was that embedding a *dbx.DB inside it would make a lot of dbx
methods publicly available on a *satellitedb.DB instance that previously
were nicely encapsulated and hidden. But after a quick look, I realized
that _nothing_ outside of satellite/satellitedb even needs to use
satellitedb.DB at all. It didn't even need to be exported, except for
some trivially-replaceable code in migrate_postgres_test.go. And once
I made it unexported, any concerns about exposing new methods on it were
entirely moot.
So I have here changed the exported *satellitedb.DB type into the
unexported *satellitedb.satelliteDB type, and I have changed all the
places here that wanted raw dbx.DB handles to use this new type instead.
Now they can just take a gander at the implementation member on it and
know all they need to know about the underlying database.
This will make it possible for some other pending code here to
differentiate between postgres and cockroach backends.
