This goes back further than Rocky but since Queens is in extended
maintenance mode upstream I figure it's best to just focus on Rocky+ for
now.

API allows source compute service/node deletion while instances are

Bug description:
This is split off from bug 1829479 which is about deleting a compute
service which had servers evacuated from it which will orphan resource
providers in placement.
A similar scenario is true where the API will allow deleting a source
compute service which has migration-based allocations for the source
node resource provider and pending instance resizes involving the
source node. A simple scenario is:
1. create a server on host1
2. resize or cold migrate it to a dest host2
3. delete the compute service for host1
At this point the resource provider for host1 is orphaned.
4. try to confirm/revert the resize of the server which will fail
because the compute node for host1 is gone and this results in the
server going to ERROR status
Based on the discussion in this mailing list thread:
http://lists.openstack.org/pipermail/openstack-
discuss/2019-November/010843.html
We should probably have the DELETE /os-services/{service_id} API block
trying to delete a service that has pending migrations.
