For nodes in excluded areas, we don't necessarily want to remove them
from the pointer, but we do want to increase the number of pieces in the
segment in case those excluded area nodes go down. To do that, we
increase the number of pieces repaired by the number of pieces in
excluded areas.

Add a RepairExcludedCountryCodes config flag for overlay for providing a list of country codes to exclude nodes from target repair selection.
Mark segments with less than repairThreshold pieces in countries not in the RepairExcludedCountryCodes as not healthy.
With this change, the repair process is not affected. The segment will be removed from the repair queue by the repairer.
Another change will handle the logic at the repairer level.

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.

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.

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. Queries for standard uploads are already cached, and node lookups for graceful exit uploads has retry logic so it isn't necessary for the nodes returned to be current.
We are no longer planning on implementing downtime penalization using
the method described in
docs/blueprints/archive/storage-node-downtime-tracking-deprecated.md.
Now, we are implementing the design described in
docs/blueprints/storage-node-downtime-tracking-with-audits.md.
This change removes the downtime estimation chores from the satellite
core as well as the package satellite/downtime. A future change will
remove the database table.

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.

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
types.

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

* change overlay.UpdateStats to allow a third audit outcome. Now it can

* 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
