CLI: `verdi computer relabel` can be relabelled to label that is parsed away in other commands

[agoscinski]

I actually wanted to cause an error and thought that the label ! would return an error, but then it worked and I could not reverse it. Maybe this label can be escaped properly. But I am not sure how and it is inconsistent that I can use it in relabel in one direction only

$ verdi computer relabel localhost !
Success: Computer 'localhost' relabeled to '!'
$ verdi computer list
