    Properly updates the SG rules when SG is changed

    When a port's security group is changed, the neutron-hyperv-agent
    receives a port_update notification. Next, the agent will call the
    HyperVSecurityGroupsDriver's prepare_port_filter, in order to process
    the new security group.

    prepare_port_filter does not remove any old rules from the port.
    update_port_filter should called instead, as it removes old rules.

    Removes 'security_group_id' and 'remote_group_id' from security
    group rules, as they make checking rule equality harder, and they
    are not used in applying the rules.
