well if we hide it like that inside the menu, then surely nobody will
use it ;)

separate panel makes it more visible IMO. it shouldn't be hidden 3
layers deep in the options menu (Host -> Firewall -> Options -> Fail2ban
-> Enable) for such a simple feature, i think a lot more people would
use it if it's placed in a visible location (Host -> Fail2ban ->
Enable). if you really insist on putting it in the firewall options menu
then i'll have to insist for it to be installed & enabled by default :)

i didn't see any good reason to not have it installed and enabled with
sane defaults since it doesn't hurt anything IMHO... that's why i went
with hard dependency instead of 'recommends' or 'suggests'.

also i wanted to have a separate API endpoint which is why i didnt go for
adding it into the options section.
though we can still make it take a property string as option i suppose.
