[CLI enchancement] Refactor directory structure for the enhanced CLI

[divyansh42]

Changes

These changes are related to TEP-0160
Modified the directory structure so that code for the enhanced CLI can be properly placed without changing the existing functionalities.
Once the enhanced CLI is ready to use, we should add a deprecated message to the existing commands and advise users to use the new commands. As of now, there is no plan to remove these commands as those can be handy for debugging purposes.

/kind misc
/release-note-none
