Title:
  compute resource providers not equal to compute nodes in deployment

Status in OpenStack Compute (nova):
  Expired

Bug description:
  Description
  ===========
  When I execute the command `nova-status upgrade check`,
  output:

  nova-status upgrade check
  +----------------------------------------------------------------------+
  | Upgrade Check Results |
  +----------------------------------------------------------------------+
  | Check: Cells v2 |
  | Result: Success |
  | Details: None |
  +----------------------------------------------------------------------+
  | Check: Placement API |
  | Result: Success |
  | Details: None |
  +----------------------------------------------------------------------+
  | Check: Resource Providers |
  | Result: Warning |
  | Details: There are 4 compute resource providers and 15 compute nodes |
  | in the deployment. Ideally the number of compute resource |
  | providers should equal the number of enabled compute nodes |
  | otherwise the cloud may be underutilized. See |
  | http://docs.openstack.org/developer/nova/placement.html |
  | for more details. |
  +----------------------------------------------------------------------+

  Steps to reproduce
  ==================
  How to replicate this?
  Remove the hosts from the openstack controller:
  nova hypervisor-list
  nova service-delete {id}

  Then run:
  su -s /bin/sh -c "nova-manage cell_v2 discover_hosts --verbose" nova
  The deleted compute node will be added again as a new node.
  run:
  nova-status upgrade check

  Expected result
  ===============
  No warning when you run:
  nova-status upgrade check

  Actual result
  =============
  You can find the warning.
  This causes issue with placement of new VM's.
  The compute host which was deleted and added again will not be considered during VM scheduling and placement.

  Environment
  ===========
  OpenStack Pike release
  Neutron Networking which is default.

  Logs and Configs
  ================
  Config as the Openstack documentation.
