> add scheduled executor to AM and event queue for async action dispatch

> Issue Type: Sub-task
> Components: appmaster

> Assignee: Steve Loughran
>
> some of the failure work: reset of sliding window, chaos events, imply
> scheduled actions. Some existing operations (AmSuicide) already use some
> threads for this
> # add a scheduled executor for pushing out this work
> # add any existing AM scheduled operations to the executor
> # add a simple event queue for the scheduled operations (and others) to push
> in actions for a pool of 1 or more handlers to process. This will stop an
> (already over-complex) sync model from getting worse
> Future: the action handler could review the queue and optimise work by
> postponing and consolidating size review operations until after any queued
> resizing actions (flex, release, lost-node, ...) have been processed
