Description

SLIDER-151 is adding new datatypes and operations between client and AM. But these won't work on Hadoop 2.6 due to proxy limitations, and will require a full switch of client code when adopted.

We can support Hadoop 2.6 by providing an IPC implementation of the new operations. That implies

1. protobuf declaration of new types + marshalling
2. extend/replace the slider client IPC interface with the new operations
3. provide IPC implementation class of SliderApplicationApi
4. AM to implement the new operations (after pulling existing IPC endpoint out of AM and into a helper class bonded to the AM via the StateView class
5. add registry location of IPC
