Tao Jiang 2ca82c25ca Add support for providing custom checkpointer (#17)
* Add credential configuration for resources

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

Signed-off-by: Tao Jiang <taoj@vmware.com>

* 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.
