Add the quarantine functionality to KRPC_Responder

[gsko]

A Quarantine has been implemented, now it just needs to be attached to KRPC_Responder.

Implementation notes:

Have the Quarantiner bind into sendQuery so that it doesn't necessarily
need to send its own querying pings. This way, the quarantiner
can observe whether the jailed node responds to ANY outbound query
giving it a higher chance of success
