" Lots of code needs storage_service just to get token_metadata from. This creates unwanted dependency loops and increases the use of global storage_service instance. This set keeps the sharded<locator::token_metadata> on main's stack and carries the references where needed. This removes the dependency on storage_service from: - storage_proxy - gossiper - redis - batchlog manager and makes the database only need it for sstables_format (will fix in one of the next sets). Also, this set is the prerequisite for controlling the copying of token_metadata instances (spotted two occurrences in bootstrap code).
