A token is necessary for managing groups.

[Kouichi Katano]

To manage groups, a request parameter has to have a token, but
 all API of managing groups do not describe a token.
A request parameter of only "GET /v3/groups" API describes a token.

There are following similar bugs:
- A token parameter is not contained in request parameters of all
  API of managing domains except for "POST /v3/domains" and
  "PATCH /v3/domains/{domain_id}".
- A token parameter is not contained in request parameters of all
  API of managing credentials except for "GET /v3/credentials".
- A token parameter is not contained in request parameters of
  "GET /v3/roles" and "GET /v3/role_assignments".
