Matt Riedemann 30a6350685 Block deleting compute services with in-progress migrations 
This builds on I0bd63b655ad3d3d39af8d15c781ce0a45efc8e3a
which made DELETE /os-services/{service_id} fail with a 409
response if the host has instances on it. This change checks
for in-progress migrations involving the nodes on the host,
either as the source or destination nodes, and returns a 409
error response if any are found.

Failling to do this can lead to orphaned resource providers
in placement and also failing to properly confirm or revert
a pending resize or cold migration.

A release note is included for the (justified) behavior
change in the API. A new microversion should not be required
for this since admins should not have to opt out of broken
behavior.

Conflicts:
      nova/tests/functional/integrated_helpers.py

NOTE(mriedem): The conflict is due to not having change
Ie991d4b53e9bb5e7ec26da99219178ab7695abf6 in Rocky.

In the unfortunate event that bugs are discovered, they should be reported to the appropriate bug tracker. If you obtained the software from a 3rd party operating system vendor, it is often wise to use their own bug tracker for reporting problems. In all other cases use the master OpenStack bug tracker, available at:

Developers

For information on how to contribute to Nova, please see the contents of the CONTRIBUTING.rst.

Any new code must follow the development guidelines detailed in the HACKING.rst file, and pass all unit tests.

Further developer focused documentation is available at:

Other Information

During each Summit and Project Team Gathering, we agree on what the whole community wants to focus on for the upcoming release. The plans for nova can be found at:
