Title:
  subnet create is not working with --use-default-subnet-pool

Status in neutron:
  New
Status in python-openstackclient:
  Invalid
Status in OpenStack SDK:
  In Progress

Bug description:
  Seems like the option is not passed properly to the API:

  $ openstack --debug subnet create --ip-version 6 --use-default-subnet-pool --ipv6-address-mode slaac --ipv6-ra-mode slaac --network mynet mysubnet
  ...

  Running the same command using the neutron CLI is working fine:

  $ neutron --debug subnet-create --name subnet6 --ip_version 6 --use-default-subnetpool --ipv6-address-mode slaac --ipv6-ra-mode slaac mynet

  ...

  So somehow this attribute is missing from the OSC's request:

  "use_default_subnetpool": true
