    [FLINK-8740] [metrics] Create new JobManagerJobMetricGroup when creating a new ExecutionGraph

    [hotfix] Create ExecutionGraph when JobMaster is started
    The ExecutionGraph is not a final resource in the JobMaster. For example, it is necessary
    to create a new ExecutionGraph when rescaling the job or when the JobMaster loses and
    regains its leadership.
