Currently the test threshold for unneeded node checkins are 30s.
The disqualification threshold was at 30s, which means, it was possible
for all the nodes to get disqualified.
Hopefully fixes#4267

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.

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.

We would like to log Node IDs and last contact successes of nodes DQd
in this manner. We would also like to avoid returning an unbounded list
of items from the db. Therefore we change the query to select a limited
number of nodes that meet the DQ conditions and iterate until 0 rows are
returned. Each column of the query is already indexed.

Full scope:
private/testplanet,satellite/{overlay,satellitedb}
Description:
In most cases, downtime tracking with audits will eventually lead
to DQ for nodes who are unresponsive. However, if a stray node has no
pieces, it will not be audited and will thus never be disqualified.
This chore will check for nodes who have not successfully been contacted
in some set time and DQ them.
There are some new flags for toggling DQ of stray nodes and the timeframes
for running the chore and how long nodes can go without contact.
