update: fix require-osd-release task

This commit fixes two issues in rolling_update.yml:

- `container_exec_cmd_update_osd` is unset in the `complete osd upgrade`
play so it never runs the command in a container.
- the 'require-osd-release' task is never applied because the condition
  looks for luminous release.

Closes: https://bugzilla.redhat.com/show_bug.cgi?id=1930164
