To save load on DNS servers, the repair code first tries to dial the
last known good ip and port for a node, and then falls back to a DNS
lookup only if we fail to connect to the last known good ip and port.
However, it looks like we are seeing errors during the client stream
Close() call (probably due to quic-go code), and those are classified
the same as errors encountered during Dial. The repairer code sees this
error, assumes that we failed to contact the node, and retries- but
since we did actually succeed in connecting the first time around, this
results in submitting the same order limit (with the same serial number)
to the storage node, which (rightfully) rejects it.
So together with change I055c186d5fd4e79560f67763175bc3130b9bc7d2 in
storj/uplink, this should avoid the double submission and avoid dinging
nodes' suspension scores unfairly.
See https://github.com/storj/storj/issues/4687.
Also, moving the testsuite directory check up above check-monkit in the
Jenkins Lint task, so that a non-tidy testsuite/go.mod can be recognized
and handled before everything breaks weirdly and seemingly randomly
later on.

We don't need to have every single test for both, only one for

which one we use.

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.

The "satellite fetch-pieces" command allows a satellite operator to
fetch as many pieces of a segment as possible, along with their
original order limits and hashes as provided by the storage nodes. The
fetched pieces and associated info will be stored on in a specified
folder as they are, rather than being RS-decoded or decrypted.
It is hoped that this will allow easier debugging of certain one-off
problems we've observed in the wild.

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.

If satellite can't find enough nodes to successfully download a segment,
it probably is not the fault of storage nodes.

work
Since we have changed the repair worker to also mark a node as audit
failure if they return a not found error, we should ignore expired
segments when possible

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.

Now instead refatoring it for segmentloop its just easier

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.

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.

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.
