Remove persistence value from table

Yea, both the Pool and VirtualServer objects seem to have delete_persistence_record methods, but they seem to delete *all* records for the pool/vs, not just an individual one.

 

 

The only idea I've had for a way to do this would be to make an iRule that detects a specially crafted URI and then uses the `persist delete` call. I'd much rather use iControl to do this though as it seems much cleaner.
