Title:
   Linux bridge agent "interface_exists_on_bridge" can be optimized

Status in neutron:
  Fix Released

Bug description:
  Currently, when lb agent needs to check if an interface exists on a
  bridge, it will get all interfaces on the bridge and looks for the
  interface:

   for filename in os.listdir(BRIDGE_INTERFACES_FS):
     if filename == interface:
       return True
     return False

  when we can directly check os.path.join(BRIDGE_INTERFACE_FS,
  interface) existence.
