Description

This PR adds a new option to the setup.sh fail2ban script to show a more detailed view on the status of all fail2ban jails using fail2ban's native status <jail> command. Effectively, the options just runs exactly that command for all jails already existing in the JAILS variable and outputs the result.
I wanted to have an option between just running the setup fail2ban sub-command without options that just returns the banned IPs and getting all details using setup fail2ban log.
This might be a bit redundant to other options, but since it is a small change that breaks nothing, I figured I could move it back here, since its usage is probably very intuitive to any fail2ban user.
