We will be needing an infrequent chore to check which nodes are in the
reverify queue and synchronize that set with the 'contained' field in
the nodes db, since it is easily possible for them to get out of sync.
(We can't require that the reverification queue table be in the same
database as the nodes table, so maintaining consistency with SQL
transactions is out. Plus, even if they were in the same database, using
such SQL transactions to maintain consistency would be slow and
unwieldy.)
This commit adds a method to the overlay allowing the caller to set the
contained status of all nodes in the nodes table at once. This is valid
because our definition of "contained" now depends solely on whether a
node appears at least once in the reverification queue. Only rows whose
contained field does not match the expectation will be updated; the
contained timestamp will not be updated for a node which is supposed to
be contained and was already contained.

we have two more fields in the database (noise_proto and
noise_public_key) that now need to go into pb.NodeAddress when
returning AddressedOrderLimits.
the only real complication is making sure type conversions between
database types and NodeURLs and so on don't lose this new
pb.NodeAddress field (NoiseInfo). otherwise this is a relatively
straightforward commit

The CASE expression used to determine which value to set
last_software_update_email to did not have an ELSE clause. Therefore,
when the node is both below the minimum version and did not receive a
version update email (no condition is true), the value would be set to
NULL.
Additionally, replace `time.Now()` with `timestamp` in the check to
determine if the email cooldown has passed.

`overlay.(*Service).UpdateReputation()` takes a "reputationChanges"
parameter, a slice of node events indicating whether we think the node's
disqualification or suspension status is changing. This is necessary so
that the overlay service can notify the nodeevents DB about these
changes.
In several cases, however, this list of events is not constructed
correctly, because of missing information about the previous state.
In most cases, this is because the node was offline, and the order limit
creation functions (which usually obtain and return the prior reputation
status) ignored that node.
This change makes it so that all callers to
`overlay.(*Service).UpdateReputation()` can be expected to provide a
correct list of change events (as correct as feasible, given that we
can't lock the node's information in the database during the entire
operation).
It ended up that there was only one caller we needed to worry about, and
that was reputation.(*Service).ApplyAudit(). So the bulk of this change
is teaching that function how to recognize when the prior reputation
status was not filled in, and fill it in.

SetNodeContained() will change the contained flag in the nodes table,
which will affect whether nodes are selected for new uploads. This flag
_should_ correlate with whether or not a given node has any entries in
the reverification queue. However, the reverification queue is intended
to be 'safely partitionable' from the nodes table, so we can't enforce
that characteristic transactionally. But this is ok; there are no dire
consequences if they are out of sync.
We will be adding a chore that updates the contained flag based on the
contents of the reverification queue periodically, if something fails
to set it directly when appropriate.

Currently, the satellite tracks connectivity information about all nodes
that have contacted it, even if we have never successfully contacted
the node back.
This behavior was leveraged during a security audit to create hundreds
of thousands of "junk nodes" in the nodes table on one satellite, which
affected performance of queries such as node selection.
With this change, we should no longer track information about nodes that
have never been successfully contacted.
Note that it will still be possible to cause the creation of "junk
node" entries in the db; the attacker just has to set up individual
publicly-routable IP+port pairs for each node as it is created, so it
can respond to a PingBack.

This is in response to community feedback that our existing reputation
calculation is too likely to disqualify storage nodes unfairly with
extreme swings up and down.
For details and analysis, please see the data_loss_vs_dq_chance_sim.py
tool, the "tuning reputation further.ipynb" Jupyter notebook in the
storj/datascience repository, and the discussion at
https://forum.storj.io/t/tuning-audit-scoring/14084
In brief: changing the lambda and initial-alpha parameters in this way
causes the swings in reputation to be smaller and less likely to put a
node past the disqualification threshold unfairly.
Note: this change will cause a one-time reset of all (non-disqualified)
node reputations, because the new initial alpha value of 1000 is
dramatically different, and the disqualification threshold is going to
be much higher.

This test had an effective config.Reputation.AuditCount = 0, meaning all
nodes that had _any_ positive audit results were considered vetted.
Because of that, only one node in the test setup was "new". And that
node was marked as being in GE, so could not be returned by node
selection.
The reason the tests still worked is because of the node selection rule
that says "if there are no new nodes at all, just get all reputable
nodes to satisfy the request".
This commit makes it so half of the nodes are vetted and half new, which
makes the test somewhat more interesting (and means we aren't
concentrating too much on testing details of behavior when AuditCount is
0).

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.

We had a bug in the stray nodes chore where nodes who had not been seen
in several months were not being DQd. We figured out that this was
happening because we were using two queries: The first to grab
nodes where last_contact_success < some cutoff, the second to DQ them
unless last_contact_success == '0001-01-01 00:00:00+00'. The problem
is that if all of the nodes returned from the first query had
last_contact_success of '0001-01-01 00:00:00+00', we would pass them to
the second query which would not DQ them. This would result in the stray
nodes DQ loop ending since we found a number of nodes to DQ less than the
limit.
The fix: add the "WHERE last_contact_success != '0001-01-01
00:00:00+00'::timestamptz" to the selection query.
