Check port value when creating firewall rule with icmp protocol

If a firewall rule was created with setting protocol as icmp
and using source/destination port no error was thrown, even though
source/destination port parameters are not used by icmp.

This patch adds a validation method that checks passed parameters
and throws an exception if they are incompatible.
