ipset: T2189: optimized firewall groups performance

This commit optimizes the speed of interaction with the ipset.

* removed extra `sudo` from `ipset` commands, because scripts that run `ipset`
commands already run under `sudo`. This gives approximately 4x performance
improvement.
* replaced logic in the `member_exists` function for port groups. Instead of
calling `ipset -T` for each port now the whole list is received in one command
and a search process is done inside Perl. This significantly improves speed for
port groups with long port ranges inside.
* delete ip address and port ranges using a single command instead deleting
each element individually.
* added the same ranges validation for address-group as for port-group.
