    Add user and project domains to ironic context

    This change also removes most of the logic from ironic's
    RequestContext to reuse the oslo_context as much as possible.
    Usage of domain_id and domain_name in policy files is deprecated
    and their support will be removed in the Pike release. domain_id
    field was removed from the context class completely, domain_name
    value now mathces the oslo_context expectations.

    ContextHook is changed too so as not to duplicate from_environ
    functional from oslo_context.

    to_dict method left as is, so that we don't break an older service
    receiving the context over RPC. It will be changed in Pike release
    to reuse the base oslo_context class' to_dict.
