[api] relationship links result in 404

[Ghanshyam Mann]

Detail doc mentioned in identity v3 api-ref for role assignment is not right one.

api-ref - http://developer.openstack.org/api-ref/identity/v3/?expanded=list-effective-role-assignments-detail

non accessible link - http://docs.openstack.org/api/openstack-identity/3/rel/role_assignments

The "Relationship" links are all JSON Home "resources". They are meant to be unique rather than functioning, so resulting in a 404 is OK.

Though, this is the second bug we've seen about this now, I'm wondering if we should update these value to actually point to the API site properly (since that was their intention in the first place)

I recalled the day when I try to update the json home, but there is comments about backwards compatibility which I think is still stand by and may be a potential risk if we change it.
