   1.Exclude is not equals to decommission,  we can refer to **HDFS**
   2.Coordinator should be stateless, if not, we need ensure multi instance data synchronization
   3.I don't think store **exclude-node-file** in hdfs and update periodically is a good choice.
   4.Whether or not controlled by coordinator，shuffle server need to expose an api to espond to this event.  we can support   controll by coordinator base on this pr
   5.Maybe we can support this function first. I think without this function, users not very willing run uniffle in the production environment. Rome wasn't built in a day, uniffle has many shortcomings now
   6.I hope you have better idea and implement it
