-----------------------------------------------------------------
[~anu] I have made changes to GenericCLI thereby fixing 'ozone scmcli' and
'ozone oz' scenarios. Also added integration test to check for various
incomplete combinations for 'ozone oz'.
Attached patch 001 for your review.

> 'ozone oz' should print usage when command or sub-command is missing

> Key: HDDS-438
> URL: https://issues.apache.org/jira/browse/HDDS-438
> Project: Hadoop Distributed Data Store
> Issue Type: Improvement
> Components: Tools
> Reporter: Arpit Agarwal
> Assignee: Dinesh Chitlangia
> Priority: Major
> Labels: newbie
> Attachments: HDDS-438.001.patch
>
>
> When invoked without the command or sub-command, _ozone oz_ prints the
> following error:
> {code:java}
> $ ozone oz
> Please select a subcommand
> {code}
> and
> {code:java}
> $ ozone oz volume
> Please select a subcommand
> {code}
> For most familiar with Unix utilities it is obvious they should rerun the
> command with _--help._ However we can just print the usage instead to avoid
> guesswork
