[FLINK-8626] Introduce BackPressureStatsTracker interface
Renames BackPressureStatsTracker into BackPressureStatsTrackerImpl and
introduce
a BackPressureStatsTracker interface. This will make testing easier when we
don't
have to set up all the different components.

[FLINK-8627] Introduce new JobStatus#SUSPENDING to ExecutionGraph
The new JobStatus#SUSPENDING says that an ExecutionGraph has been suspended
but its
clean up has not been done yet. Only after all Executions have been
canceled, the
ExecutionGraph will enter the SUSPENDED state and complete the termination
future
accordingly.

[FLINK-8546] [flip6] Respect savepoints and restore from latest checkpoints
Let the JobMaster respect checkpoints and savepoints. The JobMaster will
always
try to restore the latest checkpoint if there is one available. Next it
will check
whether savepoint restore settings have been set. If so, then it will try
to restore
the savepoint. Only if these settings are not set, the job will be started
from
scratch.

[FLINK-8629] [flip6] Allow JobMaster to rescale jobs
This commit adds the functionality to rescale a job or parts of it to
the JobMaster. In order to rescale a job, the JobMaster does the following:
1. Take a savepoint
2. Create a rescaled ExecutionGraph from the JobGraph
3. Initialize it with the taken savepoint
4. Suspend the old ExecutionGraph
5. Restart the new ExecutionGraph once the old ExecutionGraph has been
suspended

[FLINK-8633] [flip6] Expose rescaling of jobs via the Dispatcher
This commit exposes the JobMaster#rescaleJob via the Dispatcher. This will
allow it to call this functionality from a REST handler.

[FLINK-8632] [flip6] Introduce generalized asynchronous operation handlers
The asynchronous operation handlers are the generalization of the
SavepointHandlers.
They consist of a Trigger- and a StatusHandler. The TriggerHandler is used
to trigger
an asynchronous operation. The handler stores the operation future and
returns a
trigger id. The trigger id can be used to query the status of the operation
via the
StatusHandler. Once the operation has completed, the StatusHandler will
return the
result.

This commit allows the Restclient to receive generic response types. In
order
to do this, the MessageHeaders contain now information about the generic
type parameters of the response type.
