`verdi process` does not return anything

[agoscinski]

Describe the bug / Expected behavior

• No output in verdi process <SUBCOMMAND> commands for show, report, status, watch

$ verdi process show

There should be some information for the use that the process id is missing. Even more for watch it starts to run which I find strange as no id was specified.

• Also there is a inconsistency how the user is informed about missing arguments between verdi code <SUBCOMMAND> and verdi process <SUBCOMMAND>. Here compare

$ verdi process kill
Report: no active processes selected.

with

$ verdi code show 
Usage: verdi code show [OPTIONS] CODE
Try 'verdi code show --help' for help.

Error: Missing argument 'CODE'.

I would stick to the style of verdi code show everywhere, seems to me more informative and the same style is also used in verdi computer <SUBCOMMAND>. That means subcommands kill, pause, play
