Dalton Hubble 937acc4b5a Re-enable Graceful Node Shutdown feature 
* Kubelet GracefulNodeShutdown works, but only partially handles
gracefully stopping the Kubelet. The most noticeable drawback
is that Completed Pods are left around
* Use a project like poseidon/scuttle or a similar systemd unit
as a snippet to add drain and/or delete behaviors if desired
* This reverts commit 1786e34f33.

Dalton Hubble 1786e34f33 Revert Graceful Node Shutdown feature 
* Disable Kubelet Graceful Node Shutdown on worker nodes (enabled in
Kubernetes v1.25.0 https://github.com/poseidon/typhoon/pull/1222)
* Graceful node shutdown shutdown allows 30s for critical pods to
shutdown and 15s for regular pods to shutdown before releasing the
inhibitor lock to allow the host to shutdown
* Unfortunately, both pods and the node are shutdown at the same
time at the end of the 45s period without further configuration
options. As a result, regular pods and the node are shutdown at the
same time. In practice, enabling this feature leaves Error or Completed
pods in kube-apiserver state until manually cleaned up. This feature
is not ready for general use
* Fix issue where Error/Completed pods are accumulating whenever any
node restarts (or auto-updates), visible in kubectl get pods
* This issue wasn't apparent in initial testing and seems to only
affect non-critical pods (due to critical pods being killed earlier)
But its very apparent on our real clusters

Dalton Hubble 4ad473cd3c Add workaround patch to strip "search ." from resolv.conf 
* systemd adds "search ." to hosts /run/systemd/resolve/resolv.conf
on hosts with a fqdn hostname
* Kubelet v1.25 began propagating "search ." from the host node
into containers' `/etc/resolv.conf`
* musl-based DNS resolvers don't behave correctly when `search .`
is used in their `/etc/resolv.conf`. This breaks Alpine images
* Adapt the same workaround used by Openshift to strip the "search ."
* This only applies to bare-metal Typhoon nodes (where hostnames are
set to fqdn's), nodes on cloud platforms aren't affected in the
Typhoon configuration

Dalton Hubble 393a38deff Configure Graceful Node Shutdown and lengthen max inhibitor delay 
* Configure Kubelet Graceful Node Shutdown to detect system shutdown
events and stop running containers gracefully when possible
* Allow up to 30s for critical pods to gracefully shutdown
* Allow up to 15s for regular pods to gracefully shutdown
* Node will be marked as NotReady promptly, instead of having to
wait for health checks
* Kubelet uses systemd inhibitor locks to delay shutdown for a limited
number of seconds
* Raise the default max inhibitor time from 5s to 45s

Verify systemd inhibitor locks are present:

```
sudo systemd-inhibit --list
WHO     UID USER PID  COMM    WHAT     WHY                                        MODE
kubelet 0   root 4581 kubelet shutdown Kubelet needs time to handle node shutdown delay
```

Tail journal logs and then shutdown a node via systemctl reboot
or via the cloud console to watch container shutdown

Dalton Hubble 76d92e9c2d Change podman log-driver from journald to k8s-file 
* When podman runs the Kubelet container, logging to journald means
log lines are duplicated in the journal. journalctl -u kubelet shows
Kubelet's logs and the same log messages from podman. Using the
k8s-file driver alleviates this problem
* Fix Kubelet and etcd-member logs to be more readable and reduce
unneccessary Kubelet log volume
