unitctl: rename app to apps

[javorszky]

This PR achieves three separate things:

• cleans up some grouping of args with its commands to separate it from the next commands
• renamed the app to apps. Clap picks up the name of the enum as the subcommand name absent a command argument. I chose to rename the enum rather than add an option
• adds the apps line to the readme

It does not fix the whole of the readme, that's a separate issue and PR.

Closes #1423

I think it's probably worth cleaning up the references to singular unitctl app in the README.md as part of this PR

 unitctl: rename app -> apps, fix readme

Prefix should really be tools/unitctl for consistency, but I can live with just unitctl...

 whitespace: group and order command args

Signed-off-by: Gabor Javorszky <[email protected]>

Prefix should be tools/unitctl (or just unitctl depending on what you decide for the other commit). whitespace is little generic and doesn't really tell me anything...

Maybe just something like

unitctl: Whitespace fixes
