In https://github.com/openshift/installer/pull/5168, we bumped the RHCOS boot images used by the installer which brought in a number of package changes, including a cri-o bump from 1.21 -> 1.22

The bare metal IPI folks noticed failures in the CI jobs when IPv6 networking was involved that coincided with the RHCOS boot image bump.  See https://bugzilla.redhat.com/show_bug.cgi?id=1998643

In https://github.com/openshift/installer/pull/5180, the boot image bump was reverted, bringing us back to cri-o 1.21.  This improved the success rate of the CI jobs.

We were advised to try another boot image bump that included the most recent cri-o (cri-o-1.22.0-68.rhaos4.9.git011c10a.el8), but testing with that PR continues to show the failure.  See https://github.com/openshift/installer/pull/5192

Investigation into the root cause of the failure has found a few error states, but it is not entirely clear if any are the root cause for the failure.

For example:

```
$ crictl logs e6d65fe7c3563
E0902 10:11:30.001696   36592 remote_runtime.go:334] "ContainerStatus from runtime service failed" err="rpc error: code = Unavailable desc = connection error: desc = \"transport: Error while dialing dial unix /var/run/crio/crio.sock: connect: permission denied\"" containerID="e6d65fe7c3563"
FATA[0000] rpc error: code = Unavailable desc = connection error: desc = "transport: Error while dialing dial unix /var/run/crio/crio.sock: connect: permission denied" 
```

```
Another symptom is after failure to start a container, the pod restart gets stuck in SANDBOX_NOTREADY - @Arda Guclu also noticed that podman-auto-update.service was failing after the update (not clues as to why in the logs though)
```

`The only thing that comes to my mind for the SANDBOX_NOTREADY issue is https://github.com/openshift/machine-config-operator/pull/2210`

`bootkube is restarted more than 1 by getting timeout(when I checked from the green jobs, it is 1). Bootstrap apiserver is not ready until the timeout and it fails. On our local, if we wait for a long time, eventually it heals itself.`

We think we need eyes from networking + API server to help triage the current failures on https://github.com/openshift/installer/pull/5192
