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.

b39a99bae6 satellite/{overlay,satellitedb}: always show node's real online score
Previously if a node did not have audit history data for each of the
windows over the tracking period, we would give them the benefit of
the doubt and set their score to 1. This was to prevent nodes from
being suspended right out the gate. We need a minimum amount of data
to evaluate them.

However, a node who is actually failing at being online will have no
idea until they have received enough audits and we suspend them.

Instead, we will always use their real score, but use a flag to determine
whether they are eligible for suspension/dq.

2d01dd9732 satellite/satellitedb: Add online_score column to nodes table
Add online score used for the new audit history offline tracking system
to the nodes table. This allows us easy access to the node's online
score for the storagenode dashboard as well as for data analysis.

60a95d0dc9 satellite/{satellitedb,overlay}: Enable offline suspension and review period
When a node's audit history "online score" passes below a configured
threshold, the node goes into "offline suspension" mode and begins a
review period, where the operator is given an opportunity to bring their
node back online.
After the review period passes, offline suspension is turned off for the
node.

In the future, if a node still has a bad online score at the end of the
review period, it will be disqualified. This is disabled right now.
In the future, if a node is in offline suspension, it will be treated as
"unhealthy". Right now, there are no consequences for being in offline
suspension.

Minor changes:
* Moves AuditHistoryConfig out of UpdateStats/BatchUpdateStats args and
into UpdateRequest.
* Adds "now" argument to UpdateStats/BatchUpdateStats args for easy
testing.
* Changes formatting strings inside buildUpdateStatement to use specific
types.

8f60cfc4fb satellite/overlay: Add flag for enabling/disabling disqualification from suspension mode
Add a flag that allows us to easily switch disqualification from
suspension mode on or off. A node will only be disqualified from
suspension mode if it has been suspended for longer than the grace
period AND the SuspensionDQEnabled flag is true.

72b93f3120 satellite/satellitedb: disqualify suspended nodes when the grace period passes
If a node is suspended and receives an unknown or failing audit,
disqualify them if the grace period (default 1w in production) has
passed.

Migrate the nodes table so any node that is currently suspended gets
unsuspended when the satellite starts up.

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.
