[minor] Made the tank copy_apps command API access only for now.
It's an expert level command and we don't anticipate a high usage
frequency so making it API only in order to not make the command line
cognitive load greater than it already is. We should probably consider
moving a couple of the other commands into some sort of "lesser used"
section too to make it easy to spot the commonly accessed commands.
Merge branch 'master' into 25760_setup_project_wizard
