             Summary: Normalize --cmg-node and --meta-storage-node options in 
CLI
                 Key: IGNITE-22296
                 URL: https://issues.apache.org/jira/browse/IGNITE-22296
             Project: Ignite
          Issue Type: Improvement
          Components: cli
            Reporter: Aleksandr


In https://issues.apache.org/jira/browse/IGNITE-22108 I've proposed to use 
--ms-node instead --meta-storage-node but it looks like this is 
misleading/confusing for the user. 

There is also --cmg-node option that does not self-explained. The proposal of 
this issue is to rename --cmg-node to --cluster-management-group and 
--meta-storage-node to --metastorage-group.

The second proposal is to use comma-separated list to define nodes. Here is the 
example:
--cluster-management-group node1, node2, node3 --metastorage-group  node3, 
node5.

This means that we remove the support for repeating options, the following 
command is not valid anymore: cluster init --cmg-node node1 --cmg-node node2.
