--------------------------------------

Thanks [~asuresh] for driving this and [~leftnoteasy]/[~kasha] for the reviews. I'll rebase

> Based on discussions in YARN-4888, this jira proposes to replace the use of {{Priority}}
in the Scheduler infrastructure (Scheduler, Queues, SchedulerApp / Node etc.) with a more
opaque and extensible {{SchedulerKey}}.
> Note: Even though {{SchedulerKey}} will be used by the internal scheduling infrastructure,
It will not be exposed to the Client or the AM. The SchdulerKey is meant to be an internal
construct that is derived from attributes of the ResourceRequest / ApplicationSubmissionContext
/ Scheduler Configuration etc.
