Expose the following AMQP 1.0 per-object Prometheus metrics:

rabbitmq_connection_incoming_bytes_total
rabbitmq_connection_outgoing_bytes_total
rabbitmq_connection_process_reductions_total
rabbitmq_connection_incoming_packets_total
rabbitmq_connection_outgoing_packets_total
rabbitmq_connection_pending_packets
rabbitmq_connection_channels

The rabbit_amqp_writer proc:

notifies the rabbit_amqp_reader proc if it sent frames
hibernates eventually if it doesn't send any frames

The rabbit_amqp_reader proc:

does not emit stats (update ETS tables) if no frames are received or sent to save resources when there are many idle connections.
