    Fix policy check performance in 2.47+
    
    In 2.47 we introduced inlined flavors, which include extra_specs if so
    authorized. The code was doing a policy check deep in the per-instance
    handler that generated this blob. For queries with a lot of instances,
    this policy check is a lot of overhead, especially as it introduces a
    check of the policy file on disk, in case it has changed.
    
    This patch makes us calculate the permission flag once per list operation
    and pass it down to the lower layers to honor.

Bug description:
  Testing with 500 instances in ACTIVE, and 500 in ERROR state, using
  curl to pull all 1000 instances ten times in a row, 2.47 clearly shows
  a knee in the curve on average response time:
