> As discussed in FLINK-13808, we can add additional config {{taskmanager.checkpoints.max-concurrent}} that limits the number of concurrent checkpoints on the TM for safety net.
> this configure {{taskmanager.checkpoints.max-concurrent}}, and the default value for maxConcurrentCheckpoints=1 is 1 and unlimited for maxConcurrentCheckpoints > 1.
