Feature request - disable internal recursion cache

[Kevin Darcy]

Getting clients to change their resolvers can be challenging, especially 
if there are large numbers of them and many/most of them don't get their 
resolvers via DHCP.

But I think the answer to that challenge is to come up with better ways 
of managing clients, not to add a "proxy mode" to BIND.

                                                                         
                                                - Kevin
