I am not sure why we didn't do this from the very start. It seems a lot safer.
That said, I do think a longer term fix is #1190 - but that's harder (and actually would only apply to RHCOS, but we'd still want to drain classic RHEL first).

[cgwalters]

Hm, is there no master equivalent of this PR?

[cgwalters]

Also worth a least a summary of why we need this in the commit message - something like:

Since the MCO owns writing kubelet static pod configurations, we need to drain before attempting to change them so that e.g. the etcd-quorum-guard's PDB has a chance to operate. This would have also mitigated a bug in 4.1 to 4.2 upgrades - see #1177

Does this one need to have been explicitly created as a cherry-pick of the master PR? Maybe it doesn't matter and we just need an architect to do the label dance.
