Cleanup jail_exists

[vbotka]

• Update jail_exists. Returns boolean. Check create/absent only. Other comments removed.
• Change elif after break to if
• Remove todo in check_mode: use facts to check if basejail would have
  been created before. Out of scope. A play will fail if clone_from is missing.
• Fix f-string
• Fix number of returned parameters
• Fix redundant parenthesis

Tested (in the branch current)

Dear Vladimir
Thanks for your contributions to ansible-iocage - I did not use it much
in the last few years so they fell off the radar.

 Now after merging another PR to fix some null/None issue from last
week, I notice they're conflicting.
Do you still use it, and would you be interested in fixing up the conflict?
Best regards
Johannes

This one is the only conflict.

<<<<<<<< cleanup-jail_exists
            if re.match(r'(\d+|-)', _jid):
=======
            elif re.match(r'(\d+|-|None)', _jid):
>>>>>>> master

1. The 'if/elif' makes no difference because matching 'if' breaks the loop.

2. 'None' shouldn't be the 'JID' option if '-h, --header' is used. See 'iocage list -h'. But, nothing happens if you keep it.

Feel free to resolve it on your own. Preceding PRs say there is no conflict.

Occasionally I use the current branch of my fork
https://github.com/vbotka/ansible-iocage/tree/current

Would you(plural) like to submit it to any collection? Or create a 'community.freebsd' perhaps?
