[HELIX-709] Prepare controller stages for async execution
----
> Prepare controller stages for async execution
> ---------------------------------------------
>
> Key: HELIX-709
> URL: https://issues.apache.org/jira/browse/HELIX-709
> Project: Apache Helix
> Issue Type: Task
> Reporter: Hao Zhang
> Priority: Major
>
> There are a couple of stages in helix controller that can be executed
> asynchronously, but each execution should be done in order. Currently for
> helix controller, we have a thread pool for un-ordered execution, but we also
> need one for ordered execution.
> In this ticket should do the following:
> 1. Create a pool of configurable workers using DedupEventProcessor
> 2. Create AbstractAsyncBaseStage for those stages that can be executed
> asynchronously to share common code
> AC:
> Create AbstractAsyncBaseStage and DedupFIFOWorkerPool for async execution,
> pass all tests.
