* Add support for two phase checkpoints
Applications can now set a pending checkpoint, before completing the checkpoint operation. Once the application has completed its checkpoint steps, the final checkpoint will clear the pending checkpoint.
Should the checkpoint fail the attempted sequence number is provided in the InitializationInput#getPendingCheckpointSequenceNumber otherwise the value will be null.

* Adding timeout to waitForStatusMessage future call. Introducing new config properties timeoutEnabled and timeoutInSeconds. Halting the JVM if timeout is reached.
* Adding test cases for halt jvm code. Made the configuration objects for timeout optional.
* Addressing code review comments and making appropriate changes.
Updated the MultiLangDaemon to use the v2 record processor interfaces, and added features to messages passed to MultiLangDaemon clients.
These changes will require updates to the various MultiLangDaemon clients. The changes for the Python version are complete, and other versions will be updated later.
