Use the 'AS OF SYSTEM TIME' Cockroach DB clause for the Graceful Exit
(a.k.a GE) queries that count the delete the GE queue items of nodes
which have already exited the network.
Split the subquery used for deleting all the transfer queue items of
nodes which has exited when CRDB is used and batch the queries because
CRDB struggles when executing in a single query unlike Postgres.
The new test which has been added to this commit to verify the CRDB
batch logic for deleting all the transfer queue items of the exited
nodes has raised that the Enqueue method has to run in baches when CRDB
is used otherwise CRDB has return the error "driver: bad connection"
when a big a amount of items are passed to be enqueued. This error
didn't happen with the current test implementation it was with an
initial one that it was creating a big amount of exited nodes and
transfer queue items for those nodes.

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.

The test function fails randomly in the CI when runs with CRDB. There
isn't currently an explanation why the expectation of number of nodes
which exited 4 minutes ago reports 4 nodes rather than 5 and the only
clue that we have now to see if it gets remedied is to give 2 minutes
rather than 1 to the node that exited close to the time passed function
which makes the test to randomly fail.

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

At some point we might try to change original segment RS values and set Pieces according to the new values. This change adds add NewRedundancy parameter for UpdateSegmentPieces method to give ability to do that. As a part of change NewPieces are validated against NewRedundancy.

For metainfo loop we need only some of Segment fields. By removing some of them we will reduce memory consumption during loop.

The new 'consistency ge-cleanup-orphaned-data' cli command deleted
orphaned transfer queue items, but not entries in the
graceful_exit_progress table. This will delete orphaned entries
from the exit progress table too.

Using random piece num may generate the exact same key or piecenum.
Instead use fixed piecenum and key.

Testing interfaces is slightly clearer when it's in the package needing
the database rather than each individual implementation.

This enables the transfer of pieces from an on-going multipart upload.
Tests are also modified to take into account pending multipart uploads.

Add a command to the satellite for cleaning up the Graceful Exit (a.k.a
GE) transfer queue items of nodes that have exited.
The commit adds to the GE satellite DB a couple of new methods, and its
corresponding test, for performing the operations of the new command.

We now have the piece hashes verified for all segments on all production
satellites. We can remove the code that handles the case where piece
hashes are not verified. This would make easier the migration of
services from PointerDB to the new metabase.
For consistency, PieceHashesVerified is still set to true in PointerDB
for new segments.

Make metainfo.RSConfig a valid pflag config value. This allows us to
configure the RSConfig as a string like k/m/o/n-shareSize, which makes
having multiple supported RS schemes easier in the future.
RS-related config values that are no longer needed have been removed
(MinTotalThreshold, MaxTotalThreshold, MaxBufferMem, Verify).

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.

metabaseSegmentKey` TransferQueueItem
We are unifying which name (and type) we are using for value we are
using to point to segment. We want to use `key` instead of `path`.
Dedicated type `metabase.SegmentKey` was created for this purposes also.
This change is doing refactoring around gracefulexit.

..before they are transferred to another node and submitted to the
satellite as successful piece transfers, because if we submit an invalid
signature, the node will be marked as a cheater and disqualified
immediately.
These signatures should have been validated when the piece was
originally stored, but bitrot does happen and needn't be cause for an
immediate DQ.

Most places now need the NodeURL rather than the ID and Address
separately. This simplifies code in multiple places.
