firewall: Remove old rules
When a new service becomes ready or online, it is checked if its technology is more preferred than the one used by the currrent default gateway. If so, this new service becomes the new default gateway. When the tethering is enabled, a NAT rule is created to forward traffic between the interface playing the AP role and the interface connected to current default gateway. The problem comes out when the default gateway changes, because the NAT rule is disabled but not removed from the firewall rules list. Therefore, when the new rule is installed also the old rule is installed because it is still in the list. If it changes again, then three rules will be installed, and so on. They are never removed. This patch adds a deletion of all the rules from the firewall list exactly after they are disabled to avoid the described problem.
