Description

This will make the source interface more extensible in the future without breaking existing sources (after the change). Right now, the context would have methods for element emission and for retrieving the checkpoint lock for checkpointed sources. In the future this can be extended to allow emission of elements with timestamp and for dealing with watermark emission.
