Add support for Kinesis aggregation format to consume record
published by KPL.
Note: current implementation need to checkpoint the whole batch
of the de-aggregated records instead of just portion of them.
Add cache entry and exit time.

* 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.

* Add support for providing custom checkpointer
Provide a new constructor for adding checkpointer instead of alway using
default dynamodb checkpointer.
The next step is to abstract out the Kinesis into a generic stream API and
this will be bigger change and will be addressed in different PR.
Test:
Use the new construtor to inject dynamodb checkpointer and run the existing
tests.
