Cloned from https://bugzilla.redhat.com/show_bug.cgi?id=1583661

Description of problem:
When trying to add an image to a CR with some template assigned, it is not obvious from the help text how to specify the template. There is only '--uuid UUID' (of what?) without any description while I would normally grep for something like 'template' or 'image'.

Version-Release number of selected component (if applicable):
Tested on Sat 6.4 snap 5

How reproducible:
Deterministic

Steps to Reproduce:
1. # hammer compute-resource image create --help | grep -i -e template -e image

Actual results:
There is only 'UUID' without any explanation

Expected results:
I'd like to see what this UUID should specify.
