move base image to distroless

[sozercan]

Today, etcd base images are based off debian or k8s debian-base. https://github.com/etcd-io/etcd/blob/main/Dockerfile-release.amd64#L1-L2

In the past, there was a proposal to move base images from alpine to distroless: #10804 looks like they were moved to debian as an interim step #10805

Is it possible to fully move to distroless/static as a base image to reduce attack surface and image size?
