Keystone V3 "token revoke" should be supported

[Guang Yee]

OpenStack CLI does not appear to support "token revoke" when --os-identity-api-version is set to "3". It should be supported as it is a valid V3 API.

To reproduce ...

openstack --os-auth-url http://localhost:35357/v3 --os-username admin --os-password secrete --os-user-domain-id default --os-project-name admin --os-project-domain-id default --os-identity-api-version 3 token revoken gAAAAABWuNBqeIqkDsdeeLuos_YX-9kVk3Z61C5zULamvdMHwoPHXVcvQVo0arJk_FzkO4Z_CRWnym2ElsHGoACaIx85H7iXtMaWrxhvFgF6iRIJz9KNS4rJrJu9XSKJATQIRKhsufOB-_ZCZfHtsYjWZcMUmZVpQY9t_2lg6mYm5E5rZ3NY-BQ
openstack: 'token' is not an openstack command. See 'openstack --help'.
Did you mean one of these?
  token issue
  domain create
  domain delete
  domain list
  domain set
  domain show
  role add
  role assignment list
  role create
  role delete
  role list
  role remove
  role set
  role show

This works fine for V2 btw (i.e. without the "--os-identity-api-version 3" parameter).
