we should side load the newton eol role or a patched version where the package is not even requested at all due to os/kernel package name issues

That seems to be an issue as we bootstrap ansible in a earlier newton version and then bootstrapping later into newton-eol

I'm thinking I'll just make a new branch off RPC-O, maybe a 14.23.1 tag, that points to the updated branch above, and then we'll just have rpc-upgrades leapfrog checkout the 14.23.1 tag instead. It'll still be 14.23.0 but we won't have to worry about the missing artifacts that weren't created in 14.24.0.

If rcbops/openstack-ansible-openstack_hosts#4 looks good for removing the linux-modules-extras stuff, then we can merge that.

Then we can recheck this PR and see if it skips those packages and checks out the right branches:

#369

[antonym]

Merged the fix for this in.
