Cassandra filters

Request filters are invoked when a request is received from a database client, before it is forwarded to the Cassandra server. 

Response filters are invoked when a response is received from the Cassandra server, before it is forwarded to the client. 

Filters are given the opportunity to look at the packet and do whatever they want with it: let it through, modify it, or reject it. Unless it's rejected, the packet is then forwarded to its destination.
