Found a similar bug has been fixed in neutron for IPv4.
This can be added to the same, and the validation can hence be taken care in a single API call

** Project changed: python-neutronclient => neutron

Title:
  can update the gateway of ipv6 subnet with ipv6 address which has a
  leading "0" via cli

Status in neutron:
  New

Bug description:
  [Summary]
  can update the gateway of ipv6 subnet with ipv6 address which has a leading "0" via cli

  [Topo]
  devstack all-in-one node

  [Description and expect result]
  if update the gateway of ipv6 subnet with ipv6 address which has a leading "0",
   should reject leading '0's to avoid ambiguity.

  [Reproduceable or not]
  reproduceable 

  [Recreate Steps]
  1) create 1 ipv6 subnet:
  root@45-59:/opt/stack/devstack# neutron subnet-create net11 2::1/64 
  --ip-version 6 --name sub11
  Created a new subnet:

  3) if update the gateway of ipv6 subnet with ipv6 address which has a leading
   "0" via dashboard, no this issue

  4) For reference, below is the occurence of updating gateway of ipv4 subnet:
  root@45-59:/opt/stack/devstack# neutron subnet-update --gateway 1.0.0.001 sub1 
  Invalid input for gateway_ip. Reason: '1.0.0.001' is not an accepted IP address,
   '1.0.0.1' is recommended.
  root@45-59:/opt/stack/devstack#
