Merge pull request #41514 from deads2k/agg-14-register-in-local
Automatic merge from submit-queue (batch tested with PRs 41505, 41484, 41544, 41514, 41022) several issues hit while trying to make it easy to register APIs I was trying to create a script that would register all API versions on a given server and ended up hitting several problems. These are the fixes. @sttts I suspect that I won't be able to continue down the host-network approach, since that means I won't be able to use in-cluster DNS without some finagling. It *could* be set up (and we make it work as a for instance), but the simple enablement approach will be hosted on the infrastructure. I'll go back to that.
