    Better round trip for RequestContext<->Dict conversion

    Conversion of nova.context.RequestContext to and from a
    dictionary was not working properly. There is duplicate
    information as well in the serialized dict. As a first
    step i've removed request_id as it dups the one in
    oslo_context.RequestContext. However changing project_id
    and user_id to a @property is challenging at this late
    juncture. So leaving them as-is with a FIXME. The other
    issue related to the roundtrip is the stack traces that
    show up in screen-n-cpu log as mentioned in the bug
    referenced below. To avoid that added some defensive
    code ('has_attr') for now and a FIXME.
