Make create_user domain-aware for V3CredsClient
Currently create_user is just inherited from CredsClient and, therefore,
does not pass a domain_id to the /v3/users POST API call to create a new
user. As a result a domain with id "default" is used as no domain is
explicitly passed in the API call which results in 404 NOT FOUND and the
following error: "Could not find domain: default.".
The right way is passing a domain from:
1) CONF.auth.admin_domain_name
2) CONF.auth.default_credentials_domain_name
This is already taken into account when a domain_name is passed from
identity_utils during object instantiation and used for in the
create_project method specific to V3CredsClient. The API calls only
accept a domain_id which is why creds_domain field of a V3CredsClient
object is used to store an id of a domain_name domain passed via
constructor. The same can be used for create_user method specific to v3.
