Title: SHDP-439 Add support for graceful yarn app shutdown

- First stage changes
- This now brings a base support for allowing boot based
yarn app to shut itself down. Configuration is not yet
fully automated in terms of auto-configuration but
allows you to define custom beans on your app side
to do shutdown cleanly.
- Add ContainerShutdown interface to allow external beans
to shutdown containers.
- Add YarnContainerRegisterMvcEndpoint which container
can use to register itself i.e. telling its
shutdown boot endpoint.
- Add YarnShutdownCommand which can use boot shutdown
endpoint to tell appmaster to go down.
- Second stage brings more auto-configuration changes
to make things easier.
