Title:
  The allocation table has residual records when instance is evacuated
  and the source physical node is removed

Status in OpenStack Compute (nova):
  Fix Released
Status in OpenStack Compute (nova) xena series:
  Fix Released

Bug description:
  Description

  ===========

  When the compute node service is down due to a failure, we choose to
  evacuate instances located on it. After successful evacuation, the
  relevant records in allocation table will not be cleared, it will only
  be cleared when the compute service of the source node is restored.


  Unfortunately, if the failure node is down because of some
  unrecoverable failures, and compute service on it will never be
  restored, there will be residual records in the allocation table.


  Further more, if we try to delete the down compute service, record
  associated with this service will not be deleted in reource_provider
  table, because of the residual record in allocation table.


  Perhaps after a successful evacuation, we need to add operations to
  clear the allocation table, not just after the source node service is
  restored.


  Steps to reproduce

  ==================

  1.down a compute service

  2.evacuate the instances on it

  3.delete compute service with command: nova service-delete uuid


  Expected result

  ===============

  compute service is deleted successful, and resource_provider has no
  relevant record


  Actual result

  =============

  compute service is deleted successful, but resource_provider still has
  relevant record
