Idea: args shortening

[pvalena]

Can we do shortening like --playbook = --playbooks, --script = --scripts etc. then?

---

tmt plan --hel
Usage: tmt plan [OPTIONS] COMMAND [ARGS]...
Try "tmt plan --help" for help.

Error: no such option: --hel  Did you mean --help?

For command shortening I needed to do this.
