We have a code to limit segments loop in case it will hit DB to hard
but so far we didn't use this loop feature in production. This is a
simple change to avoid logic responsible for rate limiting and its
monitoring if limiting is disabled (RateLimit = 0)

Monkit calls for fast methods which are executed very frequently can
slowdown whole process. This change removes monkit calls which are not
used.
See https://review.dev.storj.io/c/storj/storj/+/8498 as an example of
speed improvement after removing monkit calls.

Currently we are tracking loop time with RunOnce method
metrics but it may give inaccurate values if loop if waiting
for observer for a ver long time. We had such case with GC
which is only loop observer in GC peer and its joning loop
every 5 days.

Currently loops wait for the coalesce duration for TriggerWait.
Let's skip the coalesce when we trigger it manually.

Not all errors from RunOnce can be retried. The context can be cancelled
with several different errors, e.g. timeout. Ensure we stop the loop
when context has errored, because none of the queries will succeed
when it has failed.

Current default is equal to hardcoded maximum of batch size
for loop listing. With this change we will bump maximum
batch size but current default won't change. We will be able to
increase it later without need for source code change.

At some point we moved metabase package outside Metainfo
but we didn't do that for satellite structure. This change
refactors only tests.
When uplink will be adjusted we can remove old entries in
Metainfo struct.

We made decision to avoid satellite shutdown when segment loop
will return error. Loop still can reeturn error but it will be logged
and we will make monitoring/alert around that error.

When the delta is very small from the bounds then the ratio calculation
doesn't work that well. Let's allow 100 from the bounds, since that
would be expected in any case.
We won't add a configuration for it, since it's not that useful.

This adds verification for the processed count and before and after
segment/objects table counts.
This adds new flag:
metainfo.segment-loop.suspicious-processed-ratio: 0.03
This defaults to 3%, which at 100M segments is 3M segments.

Loops are using custom structs to provide
segments while iterating/looping so we need
to expose new field there too.

Currently the iterate is being called in only one location so there's no
benefit in passing them as arguments over using the receiver.

In a rare case it's possible to start the loop iteration without
observers. The most likely case is that the observer is cancelled and
the coalesce timer trigger asynchronously, although being stopped.
Nevertheless, all the observers may also exit during the iteration, in
either case it should not result in an error.
If there's a probem with the observers, then they can report their own
error as they see fit.

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 want to move some of current metainfo loop observers to
segment loop. This change adds new service, similar to metainfo
loop but which is iterating only over segments.
