> 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.
