* 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.

go languaage doesn't like all-caps on const. Since KCL is mainly from
Amazon's KCL, we'd like the constant to have the exactly same name as
Amazon's KCL. Thefore, skip the lint check.

This is the core part of KCL by implementing worker.
It has exactly the same interface as Amazon's KCL. Internally,
it uses code from GoKini in order to get the library
functionaly quickly.
This is a working version. The test code worker_test.go
shows how to use this library.
Dynamic resharding feature is out of the scope of M4.
Test:
1. A Kinesis stream named "kcl-test" has been created under photon-infra
account.
2. Download your AWS Credential from IAM user page.
3. Modify the worker_test.go to fill in your aws credential.
4. hmake test
