Launchpad: #1911011 Gerrit review: https://review.opendev.org/c/openstack/charm-nova-compute/+/783371 * Functional tests for `instance-count` action on nova-compute charm. Test for `remove_from_cloud_actions` waits at the end until the nova-compute service is available again. However there's a few seconds lag until that host shows up also in `hypervisor-list` which can cause race conditions with other tests.
