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 used this to reduce initial load on the core to avoid OOM. However,
this is not a problem anymore with garbage collection running
separately.

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.

errs.Class should not contain "error" in the name, since that causes a
lot of stutter in the error logs. As an example a log line could end up
looking like:
ERROR node stats service error: satellitedbs error: node stats database error: no rows
Whereas something like:
ERROR nodestats service: satellitedbs: nodestatsdb: no rows
Would contain all the necessary information without the stutter.

Currently the loop handling is heavily related to the metabase rather
than metainfo.
metainfo over time has become related to the "public API" for accessing
the metabase data.
Currently updates monkit.lock, because monkit monitoring does not handle
ScopeNamed correctly. Needs a followup change to monitoring check.

metabase has become a central concept and it's more suitable for it to
be directly nested under satellite rather than being part of metainfo.
metainfo is going to be the "endpoint" logic for handling requests.

Check that the bloom filter creation date is earlier than the
metainfo loop system time used for db scanning.

Because the PieceTracker receives a piece count per nodes which is an
approximation of the number of nodes that they are going to be reported
by the metainfo loop so we can use as a good guess of the map's size and
initialized with it.

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.

this commit updates our monkit dependency to the v3 version where
it outputs in an influx style. this makes discovery much easier
as many tools are built to look at it this way.
graphite and rothko will suffer some due to no longer being a tree
based on dots. hopefully time will exist to update rothko to
index based on the new metric format.
it adds an influx output for the statreceiver so that we can
write to influxdb v1 or v2 directly.

Not having a skew caused an issue where:
1. Uplink calls "begin segment", where segment isn't committed to the
database.
2. Uplink stores piece X to the storage node A with timestamp 1.
3. Satellite runs garbage collection with timestamp 2.
4. Satellite sends retain request to storage node A with timestamp 2.
5. Storage node A deletes piece X, because 1 < 2.
6. Uplink calls "commit segment" with storage node A in it.
7. Download of segment fails, because A doesn't have piece X.
In production this is not an issue since the MaxTimeSkew is 72h by
default.

We don't want slowloris nodes to be able to indefinitely block
up the satellite, so add a timeout. Some monitoring inspection
showed the largest success times being on the order of 30s, so
a 1min timeout should be sufficient to kill the misbehaving nodes.

all of the packages and tests work with both grpc and
drpc. we'll probably need to do some jenkins pipelines
to run the tests with drpc as well.
most of the changes are really due to a bit of cleanup
of the pkg/transport.Client api into an rpc.Dialer in
the spirit of a net.Dialer. now that we don't need
observers, we can pass around stateless configuration
to everything rather than stateful things that issue
observations. it also adds a DialAddressID for the
case where we don't have a pb.Node, but we do have an
address and want to assert some ID. this happened
pretty frequently, and now there's no more weird
contortions creating custom tls options, etc.
a lot of the other changes are being consistent/using
the abstractions in the rpc package to do rpc style
things like finding peer information, or checking
status codes.

* nicer flags
* fix concurrency
* add concurrent workers
* initialize things
* fix tests
* close retain service
* ensure we don't have workers working on the same satellite
* ensure things compile
* fix other compilation issues:
* concurrency changes
ran this with `go test -count=1000` and it passed all of them.
- we add a closed channel so that we can select on it with
context cancellation.
- we put a once in so we only close the channel once.
- every time the queue/running state changes, we have to broadcast
because we may want to wake up N pending Wait calls or other
concurrent workers.
- because we broadcast, we don't need to do the polling in Wait
anymore.
- ensure Run doesn't start multiple times so that we don't have
to worry about concurrent Close with multiple Runs.
- hold the lock while we start workers so that a concurrent Close
with Run can't decide that there's nothing started and exit
and then have Run start things.
- make sure to poll the closed/context channels through loops
or at the start of Run calls in case Close happens first.
- these polls should be under a mutex because they have a default
case which makes it possible to schedule such that Close hasn't
executed the channel close so it starts more work.
- cancel a local Run context when it's going to exit to make sure
that any retainPieces calls have a canceled context.
- hopefully enough comments to both check my work and help readers
digest what's going on.

* concurrency fixes again
- forgot to update the gc test to use the old Wait api.
- we need to drop the lock while we wait for the workers
to exit, because they may be blocked on the condition
variable
- additionally, we need to broadcast when we close the
signal channel because the state changed: they want
to wake up and exit.

The call to monkit for functions which mostly run from the beginning to
the end of the satellite process must be done because it only causes a
little overhead.
