    Omnibus stable/liberty fix

    There are currently 3 different blocking issues in stable/liberty due
    to library releases: webob 1.5, oslo.db 3.0.0, and
    oslo.versionedobjects 0.11.0. This is a squashed fix for all of them
    as none can land without the others.

    Issue #1 - oslo.db

    Add testresources used by oslo.db fixture

    If we use oslo.db fixtures, we'll need the package or
    the next version of oslo.db release will break us.

    (Cherry-picked from 4bcc26487837b7ece7797f88622dea1b6d09bd94)

    Closes-Bug: #1503501

    Issue #2 - oslo.versionedobjects

    Drop unused obj_to_primitive() override

    This was a band-aid override until o.vo gained the obj_relationships fix
    that this method overrides. That has been in place since o.vo 0.8.0, which
    means this is long since no longer necessary (and is actually blocking our
    ability to absorb bug fixes to this code in o.vo). Further, we no longer
    use this directly because we're doing backports based on version manifests,
    which means we no longer consult child_versions _or_ obj_relationships.

    (cherry picked from commit 142f1d9cc4ace90956c665c40b1f78795f9f7e29)

    Issue #3 - webob

    Default ConvertedException code to 500

    webob 1.5.0 released on 10/11 has change f6c749011 which
    strictly enforces status codes in exceptions, and 0 is not
    a valid status code so tests fail.

    Change the default to 500 to match the default in the parent
    class in webob.
