Kubernetes Test Versions Update

Fixes #509, the test matrix was using older EOL versions of Kubernetes. This PR updates K8s to use the most recently EOL'd version (1.21) and adds all currently released versions (1.22-1.25).

Updating here - Kubernetes 1.22 and 1.23 are failing to init on the test pipeline and at first glance it looks like it could be because of the changes to containerd defaults. I'm going to test locally with a clean image of ubuntu 18.04 to get a better idea of the failure.

@Rishit-dagli do you know if containerd is a drop in replacement for dockershim? I see with #508 we replaced every reference to dockershim with the containerd path but is there any other diff we should expect? I think some of our testing still uses docker elsewhere

Updating here - was able to get it to work up to k8s 1.23 🎉
A few changes were needed to get the images we built loaded for containerd + getting kubernetes to use containerd by default.

v1.24 and v1.25 are next

Why aren't the end to end tests running in this PR? A bit strange. Hard to confirm the changes :(

They ran before I did the version bumps, if you go to the last commit before the version bumps and click on the X next to the commit message you should see it all passing minus the version changes here. Not sure why they didn't show up though :(

aha thank you!

Thanks for doing this! I know it probably took a fair bit of head-banging trial and error.
