The snapshotting code is already well isolated from the rest of
the storage_service, so it's relatively easy to move it into
independent component, thus de-bloating the storage_service.
As a side effect this allows painless removal of calls to global
get_storage_service() from schema::describe code.
Test: unit(debug), dtest.snapshot_test(dev), manual start-stop
