## Proposed changes
when gc a deleted tablet, it need 1 rocksdb read + 2 rocksdb write + 1
directory move, sometimes it will cost 20ms.
This thread will acquire the shutdown write lock and gc 200 tablets each
run, which up to 4s. So the shutdown lock will block 4s. Then happen: drop
tablet thread wait for shutdown lock for 4s, also the drop tablet thread
hold the tablet manager shard lock for 4s => create tablet thread will wait for
shard thread for 4s. => FE create partition need wait for long time.
