* 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.

Update the unit test and move integration test under test folder.
Update retry logic by switching to AWS's default retry.

* Add credential configuration for resources
Add credentials for Kinesis, DynamoDB and Cloudwatch. See the worker_test.go
to see how to use it.

* 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.

1. No functional change just upgrade to go1.11.
2. Add go mod support.
3. Make vendored copy of dependencies
Test
1. hmake
2. run worker_test.go in GoLand IDE
gas is now gosec. Need to update security scan and fix
security issue as needed.
No functional change.

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
