This aims to fix the issue described in bug 1664931 where a rebuild fails to validate the existing host with the scheduler when a new image is provided. The previous attempt to do this could cause rebuilds to fail unnecessarily because we ran _all_ of the filters during a rebuild, which could cause usage/resource filters to prevent an otherwise valid rebuild from succeeding. This aims to classify filters as useful for rebuild or not, and only apply the former during a rebuild scheduler check. We do this by using an internal scheduler hint, indicating our intent. This should (a) filter out all hosts other than the one we're running on and (b) be detectable by the filtering infrastructure as an internally-generated scheduling request in order to trigger the correct filtering behavior.

If you obtained the software from a 3rd party operating system vendor, it is often wise to use their own bug tracker for reporting problems. In all other cases use the master OpenStack bug tracker, available at:
