[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-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
