Remove the logic associated to the old transfer queue.
A new transfer queue (gracefulexit_segment_transfer_queue) has been created for migration to segmentLoop.
Transfers from the old queue were not moved to the new queue.
Instead, it was still used for nodes which have initiated graceful exit before migration.
There is no such node left, so we can remove all this logic.
In a next step, we will drop the table.

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.

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.
