When pieces fail an audit (hard fail, meaning the node acknowledged it
did not have the piece or the piece was corrupted), we will now remove
those pieces from the segment.
Previously, we did not do this, and some node operators were seeing the
same missing piece audited over and over again and losing reputation
every time.
This change will include both verification and reverification audits. It
will also apply to pieces found to be bad during repair, if
repair-to-reputation reporting is enabled.

Now that all the reverification changes have been made and the old code
is out of the way, this commit renames the new things back to the old
names. Mostly, this involves renaming "newContainment" to "containment"
or "NewContainment" to "Containment", but there are a few other renames
that have been promised and are carried out here.

Now that we are doing scalable piecewise reverifications, the code for
handling the old way of doing things (containment, pending audits,
reporting, testing) can now be removed.

This commit pulls the big switch! We have been setting up piecewise
reverifications (the workers for which can be scaled independently of
the core) for several commits now, and this commit actually begins
making use of them.
The core of this commit is fairly small, but it requires changing the
semantics in all the tests that relate to reverifications, so it ends up
being a large change. The changes to the tests are mostly mechanical and
repetitive, though, so reviewers needn't worry much.

The Reporter is responsible for processing results from auditing
operations, logging the results, disqualifying nodes that reached
the maximum reverification count, and passing the results on to
the reputation system.
In this commit, we extend the Reporter so that it knows how to process
the results of piecewise reverification audits.
We also change most reporter-related tests so that reverifications
happen as piecewise reverification audits, exercising the new code.
Note that piecewise reverification audits are not yet being done outside
of tests. In a later commit, we will switch from doing segmentwise
reverifications to piecewise reverifications, as part of the
audit-scaling effort.

NewContainment will replace Containment later in this commit chain, but
for now it is not yet being used.
NewContainment will allow a node to be contained for multiple pending
reverify jobs at a time. It is implemented by way of the reverify queue.

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.

Since we are sharing the reporting logic between repair and audit. We
need to remove metric reporting logic in reporter.

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.

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.

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.

Among other conditions, nodes fail audits by returning incorrect
data and by reaching the max reverify count, but we weren't logging
these events. This commit adds the missing logs.

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.

* change overlay.UpdateStats to allow a third audit outcome. Now it can
handle successful, failed, and unknown audits.
* when "unknown audit reputation"
(unknownAuditAlpha/(unknownAuditAlpha+unknownAuditBeta)) falls below the
DQ threshold, put node into suspension.
* 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.
