As Diana pointed out, this started failing after we started running the
job with cells v2.

I think I've figured out through my debugging patches that we're
querying the cell0 database for the instance by uuid (the marker) and
that's raising the MarkerNotFound and we don't handle it in the compute
API code, then we fail.

  There isn't anything obvious in the nova and novaclient changes around
  12/2 that would cause this.
