openshift/os: start building node image (openshift#59490)

* openshift/os: start building node image

As part of openshift/enhancements#1637, we want
to start building the node image as a layered build on top of an RHCOS
base image.

For now, don't promote this image. In the future, when we're ready to
switch CI over, it'll take the place of `rhel-coreos`.

* openshift/os: add an e2e-aws test

Now that we're building the node image in CI, we can run cluster tests
with it. Let's start simple for now with just the standard e2e-aws test.
Note that it doesn't run by default. This means that we can request it
on specific PRs only using `/test`.
