net-gateway-create's help isn't correct

[Mitsuru Kanabuchi]

"neutron help net-gateway-create" said:

  --device DEVICE Device info for this gateway device_id=<device
                        identifier>,interface_name=<name_or_identifier> It can
                        be repeated for multiple devices for HA gateways

However, actually parameter name of DEVICE is "id". Not "device_id".

$ neutron net-gateway-create --device device_id=2862ca2a-74d4-4f40-a84f-ffc32acf1f18,interface_name=eth0 ngw
Invalid input for devices. Reason: Validation of dictionary's keys failed.Expected keys: set(['id']) Provided keys: set([u'interface_name', u'device_id']).
