Title:
  nova-compute can not boot cause of old resource provider

Status in OpenStack Compute (nova):
  Invalid

Bug description:
  Description
  ===========
  The service 'nova-compute' will register resource provider in placement when it's starting.
  But if old one exist with same name, nova-compute serivce can not boot successfully.

  Steps to reproduce
  ==================
  * Boot nova-compute with hostname 'host1'
  * Create one instance placed on the compute node
  * Change hostname to 'host2' and boot nova-compute service
  * Rollback hostname to 'host1' and boot nova-compute serivce

  Expected result
  ===============
  Service 'nova-compute' booted successfully

  Actual result
  =============
  Got error 'Failed to create resource provider'

  Environment
  ===========
  1. nova: stable/rocky

      zuul: remove legacy-tempest-dsvm-neutron-dvr-multinode-full

      The job was part of the neutron experimental queue but then removed
      during the ussuri lifecycle.
