calico, cilium, occm: remove pre_upgrade and post_upgrade hooks
He have "helm.sh/hook": pre-install,pre-upgrade,post-install,post-upgrade for
- calico
- cilium
- occm to be able to install them first, before prometheus-operator and its webhooks.
We should remove pre-upgrade,post-upgrade to not trigger restarts of these components on helm upgrade.
This restart is not reported in helm diff nor kubectl diff.
