We could also add an additional message to remove registered resources
(upon Disconnect or Terminate). For most situations, the ResourceManager will
probably detect a failed container anyways.

>
> While testing Flink 1.1 I've found that the TaskManagers are logging many
> messages when registering at the JobManager.
> This is the log file:
> https://gist.github.com/rmetzger/0cebe0419cdef4507b1e8a42e33ef294
> Its logging more than 3000 messages in less than a minute. I don't think that
> this is the expected behavior.
