Is your feature request related to a problem? Please describe.

Somtimes we need change ip address of nodes including masternode,metanode and datanode. Current every node has fields such as NodeID,IPAddr.

Describe the solution you'd like.

We can set node's hostname as domain name.
When UseDomainName flag as true then Network communication with every node use domain name instead of ip address liking Hadoop and Greenplum cluster. we can just modify ip address of dns record online. see [Feature]: add name resolver for master sdk #2136 , it will update real ip periodly.
If we need change node's hostname，add cfs-cli command to list and change every node's ip or domain name.

Describe an alternate solution.

If using ip address only, add cfs-cli command to list and change every node's ip or domain name.

Anything else? (Additional Context)

I add two api, they work well:

• change metanode address
  id meta node id
  srcAddr source address, such as ip:port
  targetAddr target address, such as ip:port

curl -v 'http://127.0.0.1:17010/metaNode/changeAddr?id=[id]&srcAddr=[ip:port]&targetAddr=[ip:port]' | jq .

• change datanode address
  id data node id
  srcAddr source address, such as ip:port
  targetAddr target address, such as ip:port

curl -v 'http://127.0.0.1:17010/dataNode/changeAddr?id=[id]&srcAddr=[ip:port]&targetAddr=[ip:port]' | jq .

• if also change master ip, need to replace all kinds of *.json,then restart all service.
  if need this feature, I will create a pr.
