Dan Smith 57978de4a8 Add image type request filter
This enables the scheduler, if configured, to limit placement results
to only computes that support the disk_format of the image used
for the request.

The scheduler can now use placement to more efficiently query for hosts that support
the disk_format of the image used in a given request. The
``[scheduler]/query_placement_for_image_type_support`` config
option enables this behavior, but must not be turned on until all
computes have been upgraded to this version and thus are exposing image
type support traits.
