The main goal of this patch is to stop using get_config() glbal
when creating the sstable_writer_config instance.
Other than being global the existing get_config() is also confusing
as it effectively generates 3 (three) sorts of configs -- one for
scylla, when db config and features are ready, the other one for
tests, when no storage service is at hands, and the third one for
tests as well, when the storage service is created by test env
(likely intentionally, but maybe by coincidence the resulting config
is the same as for no-storage-service case).
With this patch it's now 100% clear which one is used when. Also
this makes half the work of removing get_config() helper.
The db::config and feature_service used to initialize the managers
are referenced by database that creates and keeps managers on,
so the references are safe.

Way too many places in code needs storage_service just for token_metadata.
These references increase the amount of get(_local)?_storage_service()
calls and create loops in components dependencies. Keep the token_metadata
separately from storage_service and pass instances' references where
needed (for now -- only into the storage_service itself).

The set make dependencies between mm and other services cleaner,
in particular, after the set:
- the query processor no longer needs migration manager
(which doesn't need query processor either)
- the database no longer needs migration manager, thus the mutual
dependency between these two is dropped, only migration manager
-> database is left
- the migration manager -> storage_service dependency is relaxed,
one more patchset will be needed to remove it, thus dropping one
more mutual dependency between them, only the storage_service
-> migration manager will be left
- the migration manager is stopped on drain, but several more
services need it on stop, thus causing use after free problems,
in particular there's a caught bug when view builder crashes
when unregistering from notifier list on stop. Fixed.
Tests: unit(dev)
Fixes: #5404
This commit makes most sleeps in gossip.cc abortable. It is now possible
to quickly shut down a node during startup, most notably during the
phase while it waits for gossip to settle.
The storage service will need this guy to initialize sub-services
with. Also it registers itself with notifiers.
That said, it's convenient to have the migration notifier on board.

1. Move tests to test (using singular seems to be a convention
in the rest of the code base)
2. Move boost tests to test/boost, other
(non-boost) unit tests to test/unit, tests which are
expected to be run manually to test/manual.
Update configure.py and test.py with new paths to tests.
