Merge pull request #23250 from huggsboson/patch-1

Automatic merge from submit-queue

Use kube-system namespace

Fixes #23153.

Sadly, kube-system isn't automatically created, so people need to make
sure to create it in their turnup scripts.  Also after creating
kube-system it can take 10+ seconds for master and proxy to show up.

I tested the equivalent of these changes locally, but not these changes
themselves as I don't have a dev/build env up, so please read carefully
and maybe try them out!
