introduces new flavor `short` for `fail2ban-client status $jail short`: output total and current counts only, without banned IPs list in order to speedup it and to provide more clear output (gh-2819), flavor `basic` (still default) is unmodified for backwards compatibility;

it can be changed later to `short`, so for full list of IPs in newer version one should better use:
  - `fail2ban-client status $jail basic`
  - `fail2ban-client get $jail banned` or `fail2ban-client banned`
