// Receiver allows the collector to receive metrics, traces and logs.
//
// The receivers that receive data via a protocol that support acknowledgements
// MUST follow this order of operations:
// - Receive data from some sender (typically from a network).
// - Push received data to the pipeline by calling nextConsumer.Consume*() function.
// - Acknowledge successful data receipt to the sender if Consume*() succeeded or
// return a failure to the sender if Consume*() returned an error.
// This ensures there are strong delivery guarantees once the data is acknowledged
// by the Collector.
