    [FLINK-3800] [jobmanager] Terminate ExecutionGraphs properly

    This PR terminates the ExecutionGraphs properly without restarts when the JobManager calls
    cancelAndClearEverything. It is achieved by allowing the method to be only called with an
    SuppressRestartsException. The SuppressRestartsException will disable the restart strategy of
    the respective ExecutionGraph. This is important because the root cause could be a different
    exception. In order to avoid race conditions, the restart strategy has to be checked twice
    whether it allows to restart the job: Once before and once after the job has transitioned to
    the state RESTARTING. This avoids that ExecutionGraphs can become orphans.
    
    Furthermore, this PR fixes the problem that the default restart strategy is shared by multiple
    jobs. The problem is solved by introducing a RestartStrategyFactory which creates for every
    job its own instance of a RestartStrategy.

    Maybe I have to increase the timeout for Travis here. Will do it.

    I increased the timeouts another time. Maybe the timeout was still set too low. Let's see.

    Unrelated test case failures. Will be merging this PR to master and the 1.0-release branch.

    The build fails with timeouts while waiting for the TMs to connect again. This is weird as the changes look unrelated to this. Do you have an idea what this might be?

    Code looks good.
    It seems that the test is still a bit unstable:
    ```
    Tests in error: 
      LeaderChangeJobRecoveryTest.before:73 » Timeout Futures timed out after [10000...
    ```
    in 3 of 5 runs:
