    Add option to control where bridges forward
    
    This adds a new config option to control where bridges can forward.
    The default behavior is unchanged, but if you specify:
    
    forward_bridge_interface=foo
    
    Then only traffic on the same bridge or going to and from the foo
    interface will be allowed. This is useful in vlan mode when a
    deployer doesn't want traffic to be routed between vlans. Note
    that forward_bridge_interface can be specified multiple times and
    should be specified once for each interface that supports floating
    ips.
