Attaching a WIP patch with tests to demonstrate the proposal in the previous comment works
Ping : [~leftnoteasy], [~kasha], [~subru], [~curino], [~kkaranasos], do take a look

The only really interesting changes are in the {{SchedulerAplicationAttempt}} class. Most
of the remaining changes are related to wiring.

> RM side changes to allow an AM to ask for change of ExecutionType.
> Currently, there are two cases:
> # *Promotion* : OPPORTUNISTIC to GUARANTEED.
> # *Demotion* : GUARANTEED to OPPORTUNISTIC.
> This is similar in YARN-1197 which allows for change in Container resources.
