Title:
  publish_service_capabilities does a fanout to all nova-compute

Status in OpenStack Compute (Nova):
  Invalid

Bug description:
  publish_service_capabilities which was added in
  https://review.openstack.org/#/c/14819/  will cause issues when there
  are a large number of compute nodes.  As every time a scheduler is
  added it will do a fanout to all of them.

  This bug is speculative.  The issue is all the compute-nodes would
  blast RPC responses back at the same time potentially causing issues
  with RPC.  furthermore if there a a large number of compute-nodes
  handling that many RPC request at the same time may bog down the
  scheduler.
