I'm happy with this version. I'd like to give @fzdarsky a chance to comment on the configuration layout and whether we want to put the storage-related settings in a subsection.

I have two questions:

• Some files under controllers/, pkg/mdns and pkg/util contain tabulation changes in the license text. Do we want these in the current PR?
• Do we need to have user documentation updated to reflect this new functionality?

I have two questions:

* Some files under controllers/, pkg/mdns and pkg/util contain tabulation changes in the license text. Do we want these in the current PR?

It seems that it won't pass the verify check otherwise. Not sure why this is being caught now though.

* Do we need to have user documentation updated to reflect this new functionality?

I'll circle back and make sure the in-repo docs are accurate.
