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.

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.

Currently the slow db was sleeping for 1s and the timeout for audit was
1s. There's a slight chance that the timeout won't trigger on such a
small difference.
Increase the slow node sleep to 10x of the timeout.
Hopefully fixes#4268

We don't use this column for anything. If you want to know if a node is

Also pass ctx to all the funcs so we can handle sleep better.

GetRandomStripe function to randomly select a segment stripe to
audit was using `segment.EncryptedSize/segment.Redundancy.StripeSize()`.
Since integer divsion truncates it leads to skipping last stripe if
its size is less than stripe size. Use `Redundancy.StripeCount` to
get correct stripe count.

If we encounter an error during the infectious error correction, we just
add it to the errlist to be logged at the worker level.
We want to make sure we know about this if it happens. Give it its own
error log and increment a monkit metric.

When a node gets enough timeouts, it is supposed to be removed
from pending_audits and get an audit failure. We would give them
a failure, but we missed the removal. This change fixes it.

"audit failed" is already used when a node fails an audit. That makes
searching for this higher level audit worker error more difficult.
Additionally, the presence of errors from the audit worker doesn't
necessarily mean the audit failed. Reword the error message to
"error(s) during audit"

When we can't complete an audit or repair, we need more information about
what happened during each individual share/piece download.
In audit, add the number of offline, unknown, contained, failed nodes to
the error log. In repair, combine the errors from each download and add
them to the error log.

package in audit
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.

In most situations where we would not get enough shares to complete
an audit, something has probably gone wrong like a forgotten delete,
and nodes should not be failed. We have an alert when this occurs.
Check the logs to see what happened. If we decide the nodes should
get audit failures, we can do it manually.

Currently, pending audit is finding segment by segment location
(path) because we want to move audit to segmentloop and we will
have only StreamID and Position we need to add columns for those
fields. Altering existing table can cause issues while
migration and deployment. Cleaner choise is to make new table.
This change contains migration with new segment_pending_audit
table that will replace pending_audits table and adjustments
to use new table in the code.
Table pending_audits will be dropped with next release.

Satellites set their configuration values to default values using
cfgstruct, however, it turns out our tests don't test these values
at all! Instead, they have a completely separate definition system
that is easy to forget about.
As is to be expected, these values have drifted, and it appears
in a few cases test planet is testing unreasonable values that we
won't see in production, or perhaps worse, features enabled in
production were missed and weren't enabled in testplanet.
This change makes it so all values are configured the same,
systematic way, so it's easy to see when test values are different
than dev values or release values, and it's less hard to forget
to enable features in testplanet.
In terms of reviewing, this change should be actually fairly
easy to review, considering private/testplanet/satellite.go keeps
the current config system and the new one and confirms that they
result in identical configurations, so you can be certain that
nothing was missed and the config is all correct.
You can also check the config lock to see what actual config
values changed.

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.

Previously the object range was not used for calculating order limit.
This meant that even if you were downloading only a small range it would
account bandwidth based on the full segment.
This doesn't fully address the accounting since the lazy segment
downloads do not send their requested range nor requested limit.

Currently the interface is not useful. When we need to vary the
implementation for testing purposes we can introduce a local interface
for the service/chore that needs it, rather than using the large api.
Unfortunately, this requires adding a cleanup callback for tests, there
might be a better solution to this problem.

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.

Currently the loop handling is heavily related to the metabase rather
than metainfo.

To fix this, add a new status called 'remove' to differentiate
