    start rpc deprecation

    we switch to work queues in Juno and made it the default rather
    than rpc. the main advantage of using RPC is it offers callback
    functionality at the expense of performance. we don't need callback
    for our use cases so it's best to stop supporting rpc and leave just
    udp and queues in our collector.
