Support Containerd 1.4.3

[meysholdt]

When upgrading from containerd 1.2, I notice:

The HostPathMount of ws-daemon fails because /run/containerd/io.containerd.runtime.v1.linux/k8s.io does not exist on the node (the last segment, k8s.io does not exist).
However, there is /run/containerd/io.containerd.runtime.v2.task/k8s.io/ which looks like (judging based on the content) like it’s what we’re looking for. Switch?

After ws-daemon came up, workspaces fail with error MountVolume.SetUp failed for volume "dev-net-tun" : hostPath type check failed: /dev/net/tun is not a file

@meysholdt I am seeing this as documented in the chart values, maybe make it a default.

/dev/net/tun was #3258 and may have been fixed since (?): 44a47ef

@wulfthimm is working on it

/dev/net/tun failure is fixed in #4596
