Updated from global requirements and workaround testr/pbr issue

The fix for pbr is in 6e472b4905411a39e993c81c382a27ca9c771ef5 but
rather than wait for that to be released in pbr on stable/kilo we
will workaround it here so we can get stable/kilo and stable/liberty
gates unblocked, then come back and cleanup later.
