db6bc6503d satellite/metainfo: Update metainfo RS config to more easily support multiple RS schemes.
Make metainfo.RSConfig a valid pflag config value. This allows us to
configure the RSConfig as a string like k/m/o/n-shareSize, which makes
having multiple supported RS schemes easier in the future.

RS-related config values that are no longer needed have been removed
(MinTotalThreshold, MaxTotalThreshold, MaxBufferMem, Verify).

dc67ce74c9 satellite: remove IsUp field from overlay.UpdateRequest
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.

92a2be2abd satellite/metainfo: get away from using pb.Pointer in Metainfo Loop
As part of the Metainfo Refactoring, we need to make the Metainfo Loop
working with both the current PointerDB and the new Metabase. Thus, the
Metainfo Loop should pass to the Observer interface more specific Object
and Segment types instead of pb.Pointer.

After this change, there are still a couple of use cases that require
access to the pb.Pointer (hence we have it as a field in the
metainfo.Segment type):
1. Expired Deletion Service
2. Repair Service

It would require additional refactoring in these two services before we
are able to clean this.

bb7be23115 satellite/{audit,overlay,satellitedb}: enable reporting offline audits
- 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.

1aeb14e65e satellite/audit: do not delete expired segments
A year ago we made the audit service deleting expired segments.
Meanwhile, we introduced an expired deletetion sub-service in the
metainfo service which sole purpose is deleting expired segments.

Therefore, now we are removing this responsibility from the audit
service. It will continue to avoid reporting failures on expired
segments, but it would not delete them anymore.

We do this to cleanup responsibilities in advance of the metainfo
refactoring.

360ab17869 satellite/audit: use LastIPAndPort preferentially
This preserves the last_ip_and_port field from node lookups through
CreateAuditOrderLimits() and CreateAuditOrderLimit(), so that later
calls to (*Verifier).GetShare() can try to use that IP and port. If a
connection to the given IP and port cannot be made, or the connection
cannot be verified and secured with the target node identity, an
attempt is made to connect to the original node address instead.

A similar change is not necessary to the other Create*OrderLimits
functions, because they already replace node addresses with the cached
IP and port as appropriate. We might want to consider making a similar
change to CreateGetRepairOrderLimits(), though.

The audit situation is unique because the ramifications are especially
powerful when we get the address wrong. Failing a single audit can have
a heavy cost to a storage node. We need to make extra effort in order
to avoid imposing that cost unfairly.

Situation 1: If an audit fails because the repair worker failed to make
a DNS query (which might well be the fault on the satellite side), and
we have last_ip_and_port information available for the target node, it
would be unfair not to try connecting to that last_ip_and_port address.

Situation 2: If a node has changed addresses recently and the operator
correctly changed its DNS entry, but we don't bother querying DNS, it
would be unfair to penalize the node for our failure to connect to it.

So the audit worker must try both last_ip_and_port _and_ the node
address as supplied by the SNO.

We elect here to try last_ip_and_port first, on the grounds that (a) it
is expected to work in the large majority of cases, and (b) there
should not be any security concerns with connecting to an out-or-date
address, and (c) avoiding DNS queries on the satellite side helps
alleviate satellite operational load.

e7f2ec7ddf satellite/audit: fix sanity check for verify-piece-hashes command
The VerifyPieceHashes method has a sanity check for the number pieces to
be removed from the pointer after the audit for verifying the piece
hashes.

This sanity check failed when we executed the command on the production
satellites because the Verify command removes Fails and PendingAudits
nodes from the audit report if piece_hashes_verified = false.

A new temporary UsedToVerifyPieceHashes flag is added to
audits.Verifier. It is set to true only by the verify-piece-hashes
command. If the flag is true then the Verify method will always include
Fails and PendingAudits nodes in the report.

Test case is added to cover this use case.

b409b53f7f cmd/satellite: command for verifying piece hashes
Jira: https://storjlabs.atlassian.net/browse/PG-69

There are a number of segments with piece_hashes_verified = false in
their metadata) on US-Central-1, Europe-West-1, and Asia-East-1
satellites. Most probably, this happened due to a bug we had in the
past. We want to verify them before executing the main migration to
metabase. This would simplify the main migration to metabase with one
less issue to think about.

5d21e85529 satellite/audit/queue: Separate audit queue into two separate structs.
* The audit worker wants to get items from the queue and process them.
* The audit chore wants to create new queues and swap them in when the
old queue has been processed.

This change adds a "Queues" struct which handles the concurrency
issues around the worker fetching a queue and the chore swapping a new
queue in. It simplifies the logic of the "Queue" struct to its bare
bones, so that it behaves like a normal queue with no need to understand
the details of swapping and worker/chore interactions.

cadb435d25 {satellite/audit, private/testplanet}: remove ErrAlreadyExists, run 2 audit workers in testplanet
Since we increased the number of concurrent audit workers to two, there are going
to be instances of a single node being audited simultaneously for different segments.
If the node times out for both, we will try to write them both to the pending audits
table, and the second will return an error since the path is not the same as what
already exists. Since with concurrent workers this is expected, we will log the
occurrence rather than return an error.

Since the release default audit concurrency is 2, update testplanet default to run with
concurrent workers as well.

26fce54b11 satellite/audit: increase MinDownloadTimeout in TestReverifySlowDownload
This test failed due to a timeout on a download which is supposed to
succeed. The testplanet default for the value is 5 seconds, but here
it is 500 milliseconds.

It looks like this is due to the fact that later in the test we need to
wait for a slow node to timeout, so we cut the timeout shorter to reduce
test time.

This PR increases the timeout to 1 second. Still not too long to wait, but
gives us twice as much time to download, decreasing the likelihood that we
see the timeout error.

03e5f922c3 satellite/overlay: updates node with a vetted_at timestamp if they meet the vetting criteria
What: As soon as a node passes the vetting criteria (total_audit_count and total_uptime_count
are greater than the configured thresholds), we set vetted_at to the current timestamp.

Why: We may want to use this timestamp in future development to select new vs vetted nodes.
It also allows flexibility in node vetting experiments and allows for better metrics around
vetting times.

Please describe the tests: satellitedb_test: TestUpdateStats and TestBatchUpdateStats make sure vetted_at is set appropriately
Please describe the performance impact: This change does add extra logic to BatchUpdateStats and UpdateStats and
commits another variable to the db (vetted_at), but this should be negligible.

0c8c11b251 satellite/audit: add not_enough_shares_for_audit counter
We have been using the SQL expression `name='(*Verifier).Verify' AND
error_name='not enough shares for successful audit'` thus far to detect
cases of this problem and alert on them. Unfortunately, since this
rarely (hopefully never) happens, influxdb has no data for most of the
auditor instances, and when it has no data for a time series, it returns
no columns either. This makes Redash upset when it tries to perform a
query for an alert and can't find the column whose value it expects to
check.

This change should make it so zero values are reported when the problem
has not happened, and higher values when it has.

e1a443b04a private/testplanet: allow modifying created database
Instead of providing the database from outside to testplanet create it
inside and then allow wrapping and modifying it. This is more convenient
to use.

2f991b6c56 satellite/{overlay, satellitedb}: account for suspended field in overlay cache
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

8b72181a1f satellite/{audit,overlay,satellitedb}: implement unknown audit reputation and suspension
* 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.
