* Release shard lease after shutdown
Currently, only local cached shard info has been removed when worker losts the
lease. The info inside checkpointer (dynamoDB) is not removed. This causes
lease has been hold until the lease expiration and it might take too long
for shard is ready for other worker to grab. This change release the lease
in checkpointer immediately.
The user need to ensure appropriate checkpointing before return from
Shutdown callback.
Test:
updated unit test and integration test to ensure only the shard owner
has been wiped out and leave the checkpoint information intact.
