Title:
  Updating subnet fails with both allocation-pools and gateway_ip
  specified

Status in neutron:
  Fix Released

Bug description:
  Subnet updating with both allocation-pool and gateway_ip options is
  failing if parameter of the gateway_ip conflicts with allocation pools
  in db even if the parameter of gateway_ip not conflicts with
  parameters of the allocation-pool.

  Steps to reproduce:
  1.  Create one network.
  2.  Create one subnet under the above network with allocation pool provided. i.e “neutron subnet-create --name <NAME> --allocation-pool start=<start IP>,end=<end IP> <NETWORK>  <CIDR>”
  3.  Issue command "neutron subnet-update <NAME> --gateway_ip <GATEWAY_ IP> --allocation-pool start=<new start IP>,end=<new end IP>" where <GATEWAY_IP> is not in the range <new start IP>-<new end IP> but in the current allocation pool range <start IP>-<end IP>.

  Actual results:
  The above command fails with "gateway ip <GATEWAY_IP> conflicts with allocation pool <start IP>-<end IP>" where <start IP>-<end IP> is the current allocation pool range of the above subnet.

  Expected results:
  success-full subnet updated

  Example of failure:
  + neutron net-create test-net
