Fix start, stop, and restart

[vbotka]

• Remove unused vars rc,out,_msg
• Add {out} to success msg instead of {rc}
• Stop jail if not down
• Jail start, stop, and restart functions always return
  changed=True. Start if not up. Stop if not down. Restart without
  checking state (iocage util will start jail if down).

All tests passed. See the previous PR.

Changes lgtm 👍 but it now conflicts with what I've merved from #35 - could you please your changes on master branch?

You don't need to open a new pull request for this, just do git checkout master ; git pull origin master ; git checkout fix-start-stop ; git rebase -i master ; git push --force origin fix-start-stop or something along these lines

Actually, I was able to resolve it online here. Thank you!

The reason I wanted you to rebase it is to not clutter the history with merges going from master into a feature branch, that will then get merged back into master again ;-)
