Title:
  Nova host aggregate cannot sync to placement

Status in OpenStack Compute (nova):
  Fix Released

Bug description:
  Description
  ===========
  We are using the nova stein version.
  When adding/removing host from aggregate, nova should sync the host aggregate to placement resource provider aggregate as well. But from our test, it is not working.

  Steps to reproduce
  ==================
  1. Check a specific compute node resource provider aggregate
  2. Create a new host aggregate and add the compute node into the aggregate
  3. Check the compute node resource provider aggregate again to see if the additional aggreate is added

  (We got the similar error when removing host from an existing
  aggregate)

  Expected result
  ===============
  An additional resource provider aggregate for the compute node

  Actual result
  =============
  No change.

  Logs & Configs
  ==============

  Note:
  cc2 is the hostname for the compute node, but we use fqdn for the hypervisor. So the name of the resource provider is fqdn(with domain). I think that is the reason why the resource provider cannot be found.
