             Summary: Change the style of named options in the CLI
                 Key: IGNITE-16512
                 URL: https://issues.apache.org/jira/browse/IGNITE-16512
             Project: Ignite
          Issue Type: Improvement
          Components: general
            Reporter: Roman Puchkovskiy
            Assignee: Roman Puchkovskiy
             Fix For: 3.0.0-alpha5


Some named CLI options may have multiple values. There are few different ways 
to use such multi-valued options from the CLI:
 # --nodes "one two three" (that is, put all the values in the same command 
line argument)
 # --nodes one two three (that is, put each value as a separate command line 
argument)
 # --node one --node two --node three (repeat the option name with each value; 
please note that here the option name is in singular form)

A team-wide discussion was caried on in a Slack channel, and it was suggested 
that we use option 2. But the existing commands (like 'module add ' with --repo 
option) already use option 3.

The style needs to be changed.
