What type of PR is this?

/kind bug

What this PR does / why we need it:
This PR addresses an issue with ansible templating that results in the etcd cluster failing to be upgraded when etcd_deployment_type == "kubeadm".

etcd_deployment_type == "kubeadm" | bool | lower

The line above always results in False since ansible evaluates conversion operator | before the comparison operator ==.

This PR also adds a CI job to the periodic (nightly) run to test the upgrade with etcd managed by kubeadm so we can catch this kind of breakage in the future.

Which issue(s) this PR fixes:

Fixes #8721
