Can we modify this patch to do Himanshu's suggestion? add a deleteRecursive
call at the end of all these conditional checks

I'm worried that if a customer has their own custom znodes. Cleaning the data
we don't know may cause data loss for them if they're not aware of this side
effect. Even sideline those znodes, it will also cause pain for them to move
them back. So far all znodes we know are covered after the fix. Therefore,
unknown znodes if there is any mostly likely are users data.
IMHO, it's better to be conservative to work on data that we know.
