 The Loki receiver implements the [Loki push api](https://grafana.com/docs/loki/latest/clients/promtail/#loki-push-api) as specified [here](https://grafana.com/docs/loki/latest/api/#push-log-entries-to-loki). 
 It allows Promtail instances to specify the open telemetry collector as their lokiAddress.
