The storage_proxy represents the entire cluster, so there's never a need
to access it on a remote shard; the local shard instance will contact
remote shard or remote nodes as needed.
Simplify the API by passing storage_proxy references instead of
seastar::sharded<storage_proxy> references. query_processor and
other callers are adjusted to call seastar::sharded::local() first.
