Do we have a BZ for this? This looks like something we'll want to backport.
It also looks like we'll have to do the same thing for Cinder CSI.

LGTM otherwise.

/hold

As it turned out, kube-rbac-proxy is not coded/configured properly to handle client certificate authentication yet. I am in the process of fixing that. It does not hurt to get this in. But the functionality will only work after that fix.

I am putting a hold on this. But if it is preferred to merge this first, it can be /unhold.
