Add support for kots on arm64

Description

Currently, we are unable to use kots install and schedule the console on arch arm64. The kotsadm pod will not be scheduled:

More info: https://github.com/replicatedhq/kots/issues/896

Motivation

• Add support for Apple Silicon
• Allow users and maintainers to use and test the solution into for example Apple Silicon.
• Allow users to use the solution in any linux arm64 env

Thank you for opening this issue, @camilamacedo86. This is something that we hope to support in the future, and SC34569 is our internal tracker for this.

👍 on this one, currently I can't test KOTS locally on minikube, I'm forced to use a remote cluster

Hi folks, just got a macbook with an M2 chip and removing the arm64 affinity rule in the kots deployment allows it to be scheduled and as far as I can tell, it works without a problem after that.

Was the kots binary made arm64 compatible and it's now just a matter of removing that restriction in the deployment? Here are the changes I made to get it to work.

I request at least an option --ignore-arch or something so we can do it. It works and might not be compiled right, but with rosetta installed it works without an issue
