Merge pull request #37019 from pipejakob/e2e-anywhere-pr

Automatic merge from submit-queue

Add kubernetes-anywhere as a new e2e deployment option.

This change adds support for using `kubernetes-anywhere` as a deployment option for hack/e2e.go. This work is toward the larger goal of being able to run e2e tests against `kubeadm` clusters, which `kubernetes-anywhere` supports.

**Release note**:
```release-note
Add kubernetes-anywhere as a new e2e deployment option
```

The configuration in `getConfig()` comes mostly from the defaults in `kubernetes-anywhere`. In the future, we can add more plumbing to override them via CLI flags.
