    [backport] [FLINK-3347] [akka] Add QuarantineMonitor which shuts a 
quarantined actor system and JVM down

    This is a back port for release 1.1.
    
    The QuarantineMonitor subscribes to the actor system's event bus and 
listens to
    AssociationErrorEvents. These are the events which are generated when the 
actor system
    has quarantined another actor system or if it has been quarantined by 
another actor
    system. In case of the quarantined state, the actor system will be shutdown 
killing
    all actors and then the JVM is terminated.
    
    Per default the `QuarantineMonitor` is not started for the `TaskManagers`.

    Add configuration switch to enable the quarantine monitor for TaskManagers
    
    Per default the QuarantineMonitor is disabled for TaskManagers in order to 
not change
    the behaviour of 1.1.

>
> There are cases where Akka quarantines remote actor systems. In that case, no 
> further communication is possible with that actor system unless one of the 
> two actor systems is restarted.
> The result is that a TaskManager is up and available, but cannot register at 
> the JobManager (Akka refuses connection because of the quarantined state), 
> making the TaskManager a useless process.
> I suggest to let the TaskManager restart itself once it notices that either 
> it quarantined the JobManager, or the JobManager quarantined it.
> It is possible to recognize that by listening to certain events in the actor 
> system event stream:
