    Move port validation support into the driver

    Each firewall driver have specific checks to do on port validation (like
    checks if the VIF port type corresponds to a type supported by the driver
    (aka the SDN controller)). This patch adds two methods to the driver
    interface to validate if the VM or the router port is supported (just
    have to return a boolean).
