Cannot create guest after certificate relation is added

[Liam Young]

When the certificate relation is added to the api services in the cloud it sometimes causes services to be unable to talk to one another. This seems to be due to them attempting to talk http to https services.

This is related to Bug #1826382

    Watch & react to placement and neutron ep changes.

    Request to be informed of changes to placement and neutron changes.
    If a placement change occurs restart nova-scheduler as it will
    cache the old endpoint url and tell nova-compute to restart its
    services as they will have done the same.

I confirmed the same symptom in OpenStack Train environment using Placement charm.
After upgrading the nova-cloud-controller to cs:~openstack-charmers-next/nova-cloud-controller-475, the issue was mitigated.
Since this is affecting customer's deployment, I have subscribed this to field-high.
Can this fix be backported to stable charm as well?
Thank you

Change abandoned by Nobuto Murata (<email address hidden>) on branch: stable/20.02
Review: https://review.opendev.org/713356
Reason: Dropping this review for the time being. The bug is related to 3 charms at least and charm-helpers so I will leave it to OpenStack Charmers for proper backports altogether.

Removing placement and nova-compute as this bug is resolved via changes already landed into other projects.
