Previously, k3s.service was failing when the EnvironmentFile does not exist:
```

Feb 02 17:17:30 suda-ws01 systemd[1]: k3s.service: Failed to run 'start' task: No such file or directory

Remove symlinks to /run/{netns,containerd} so that rootless mode can create their own /run/{netns,containerd}.

* Replace k3s cloud provider wrangler controller with core node informer
Upstream k8s has exposed an interface for cloud providers to access the
cloud controller manager's node cache and shared informer since
Kubernetes 1.9. This is used by all the other in-tree cloud providers;
we should use it too instead of running a dedicated wrangler controller.
Doing so also appears to fix an intermittent issue with the uninitialized
taint not getting cleared on nodes in CI.

Problem:
While using ZFS on debian and K3s with docker, I am unable to get k3s working as the snapshotter value is being validated and the validation fails.
Solution:
We should not validate snapshotter value if we are using docker as it's a no-op in that case.
