Bugfix for ufw to support "logging" properly:
It's a separate parameter so updated docs and set it as mutually exclusive param.
Also due to an array construction typo it was not working in any situation (ufw LOGLEVEL was passed to cmd instead of ufw logging LOGLEVEL).

Also fixed doc and parameters parsing typo ("choises" should be "choices")
