[RFE] Add domains to ironic context

[Vladyslav Drok]

Currently, user domain and project domain information is not included in ironic context. With the planned complete switch to keystone v3, they should be included, to be able to fully use v3 functional.

    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.
