    [FLINK-7668] Add ExecutionGraphCache for ExecutionGraph based REST handlers
    
    The ExecutionGraphCache replaces the ExecutionGraphHolder. Unlike the latter, the former
    does not expect the AccessExecutionGraph to be the true ExecutionGraph. Instead it assumes
    it to be the ArchivedExecutionGraph. Therefore, it invalidates the cache entries after
    a given time to live period. This will trigger requesting the AccessExecutionGraph again
    and, thus, updating the ExecutionGraph information for the ExecutionGraph based REST
    handlers.
    
    In order to avoid memory leaks, the WebRuntimeMonitor starts now a periodic cleanup task
    which triggers ExecutionGraphCache.cleanup. This methods releases all cache entries which
    have exceeded their time to live. Currently it is set to 20 * refreshInterval of the
    web gui.
    
    This closes #4728.

    [FLINK-7695] [flip6] Add JobConfigHandler for new RestServerEndpoint

    [FLINK-7708] [flip6] Add CheckpointConfigHandler for new REST endpoint
    
    This commit implements the CheckpointConfigHandler which now returns a
    CheckpointConfigInfo object if checkpointing is enabled. In case that
    checkpointing is disabled for a job, it will return a 404 response.
