I believe we can close this out.  PKI tokens are now the default, which
don't require as many round trips.  There may have been improvements
from before PKI tokens, as well.

Title:
  Excessive number of calls to keystone auth on instance boot

Status in OpenStack Compute (Nova):
  Invalid

Bug description:
  Using commit ebec34e374bd9ec5354e3648a6e8f3ce26c951b5 and the keystone
  middleware, I'm noticing an excessive number of auth requests to the
  keystone server occurring on a simple boot of an instance from both
  Nova and Glance.  Because of this, I'm seeing some 9-10 second times
  when running a nova boot.

  Watching the keystone server logs from this, a single boot can
  generate 8000 lines of verbose logs for a single boot in keystone
  (700k in size).
