Comment out DaemonSet update type fields and remove the code that depends on it.

Leaving the type fields as comments for reference and reminder. But
deleting the conversion, defaulting and validation code. They can
always be brough back from the previous PR once the types are
introduced. Because builds break without them anyway that serves as a
reminder, so there is no need to leave them commented out.
