Improve Placement special operation
Improve the instructions that cover the introduction of the placement charm by mentioning that nova-compute payload upgrade should follow nova-cloud-controller payload upgrade. Correct the payload upgrade order on the openstack-upgrade page by putting nova-compute after nova-cloud-controller. The former was recently moved up due to minimise OVN control plane downtime but the current fix is essential. The upgrdae-charms page was likewise updated. Closes-Bug: #1970266 Change-Id: Ic564bfd649bd8d3ba435577b7e7d2f472992a1c6
