https://github.com/apache/flink/pull/2353
I addressed the comments by @tillrohrmann and @wenlong88
- turning the registration object into a reusable utility that can also
be used for the JobMaster registration
- I made the registration object behave more like a cancelable future.
That way, it needs not use the TaskExecutor's main-thread-execution-context for
its retries.
This looks actually pretty nice now. Will merge this to allow other people
to build on top of it. Will provide tests ASAP.
