This patch finishes the placement aware repair.
We already introduced the parameters to select only the jobs for specific placements, the remaining part is just to configure the exclude/include rules. + a full e2e unit test.

This feature flag was disabled by default to test it slowly. Its enabled
for some time on one production satellite and test satellites without
any issue. We can enable it by default in code.

Currently, we have issue were while counting unhealthy pieces we are
counting twice piece which is in excluded country and is outside segment
placement. This can cause unnecessary repair.
This change is also doing another step to move RepairExcludedCountryCodes
from overlay config into repair package.

This change makes dial timeout configurable and change it also from
defatul 20s to 5s. Main motivation is that during repair we often loose
lots of time to dial which eventually will fail. New timeout should be
still enough to dial but we will move forward quicker to next node if
that one will fail.
Timeout is also applied directly as context timeout in case we will
use noise of tcp fast open one day.

Segment repairer should take into account segment 'placement' field
and remove or repair pieces from nodes that are outside this placement.
In case when after considering pieces out of placement we are still above
repair threshold we are only updating segment pieces to remove
problematic pieces. Otherwise we are doing regular repair.

It seems that the "what pieces are clumped" code does not work right, so
this logic is causing repair overload or other repair failures.
Hide it behind a flag while we figure out what is going on, so that
repair can still work in the meantime.

The following tests should be made less flaky by this change:
- TestFailedDataRepair
- TestOfflineNodeDataRepair
- TestUnknownErrorDataRepair
- TestMissingPieceDataRepair_Succeed
- TestMissingPieceDataRepair
- TestCorruptDataRepair_Succeed
- TestCorruptDataRepair_Failed
This follows on to a change in commit 6bb64796. Nearly all tests in the
repair suite used to rely on events happening in a certain order. After
some of our performance work, those things no longer happen in that
expected order every time. This caused much flakiness.
The fix in 6bb64796 was sufficient for the tests operating directly on
an `*ECRepairer` instance, but not for the tests that make use of the
repairer by way of the repair queue and the repair worker. These tests
needed a different way to indicate the number of expected failures. This
change provides that different way.

Reputation updates during repair currently consumes a lot of database
resources. Sometimes increasing the rate of repair is more important
than auditing a node based on whether they have or don't have the
correct piece during repair. This is the job of the audit service.
This commit is to implement an intermediate solution from this issue: https://github.com/storj/storj/issues/5089
This commit does not address the more in-depth fix discussed here: https://github.com/storj/storj/issues/4939

We want to use StreamID/Position to identify injured
segment. As it is hard to alter existing injuredsegments
table we are adding a new table that will replace existing
one. Old table will be dropped later.

This is part of metaloop refactoring. We plan to remove
irreparable at some point but there was not time for it.
Now instead refatoring it for segmentloop its just easier
to drop it.
Later we still need to drop table with migration step.

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.

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.

Add flag to satellite repairer, "InMemoryRepair" that allows the
satellite to decide whether to download the entire segment being
repaired into memory (this is what the satellite already does), or to
download it into temporary files on disk that will be read from in the
upload phase of repair.
This should help with handling high repair traffic on satellites that
cannot afford to spend 64mb of memory per repair worker.
Updates tests to test repair for both in memory and to disk.

Previously, we were simply discarding rows from the repair queue when
they couldn't be repaired (either because the overlay said too many
nodes were down, or because we failed to download enough pieces).
Now, such segments will be put into the irreparableDB for further
and (hopefully) more focused attention.
This change also better differentiates some error cases from Repair()
for monitoring purposes.

This new repair timeout (configured as TotalTimeout) will include both
the time to download pieces and the time to upload pieces, as well as
the time to pop the segment from the repair queue.
This is a move from Github PR #3645.

this commit updates our monkit dependency to the v3 version where
it outputs in an influx style. this makes discovery much easier
as many tools are built to look at it this way.
graphite and rothko will suffer some due to no longer being a tree
based on dots. hopefully time will exist to update rothko to
index based on the new metric format.
it adds an influx output for the statreceiver so that we can
write to influxdb v1 or v2 directly.
