[FLINK-4711] Let the Task trigger partition state requests and handle their
responses
This PR makes changes the partition state check in a way that the Task is
now responsible
for triggering the state check instead of the SingleInputGate. Furthermore,
the operation
returns a future containing the JobManager's answer. That way we don't have
to route the
response through the TaskManager and can add automatic retries in case of a
timeout.
The PR removes the JobManagerCommunicationFactory and gets rid of the
excessive
PartitionStateChecker and ResultPartitionConsumableNotifier creation.
Instead of creating
for each SingleInputGate one PartitionStateChecker we create one for the
TaskManager which
is reused across all SingleInputGates. The same applies to the
ResultPartitionConsumableNotifier.
This PR is also a simplification for the Flip-6 implementation.
