Short description

There should be a way to remove an entry from a partitioned cache.

Usecase

When using a partitioned cache (using multiple tags using gettag()) we have a partitioned packet cache, eg for two types of users.

There is a way to wipe all info about a certain qname, but that wipes it from everything (packetcache, other caches, ...). (rec_control wipe-cache qname).

It would offer a lot of control to the admins if we could just wipe the packet cache and even better if we could just the packet cache for a particular tag.

Description

Would propose to have something like a rec_control wipe-pcache [tag] [qname] command which would just remove it from the Packet Cache but only for that pc tag.
