There is some history here.
https://github.com/ansible/awx/pull/7190 <- This PR was an attempt at fixing a
bug notting ran into where some jobs on k8s installs would get stuck in Waiting
forever.
The PR mentioned above introduced a bug where there are no instance groups on a
fresh k8s-based install. This is because this process currently happens in the
launch scripts, before the database is up.
With this patch, queue / instance group registration happens in the heartbeat,
right after auto-registering the instance.
