Public bug reported:

To fill the request group - resource provider mapping nova needs to look
at the allocation that is made in placement as well as the traits of the
used providers. These are explicit placement calls today. However it
turns out that the Selection object already contains the allocation data
so one of the extra placement call can be removed. This change can lead
to a bit better performance.
