Ingest Prometheus remote-write metrics into a Chronosphere Telemetry Pipeline

Steps

1. Add the prometheus_remote_write source plugin to a Telemetry Pipeline and set the required port parameter for the pipeline to listen on.
2. Point Prometheus's (or another remote-write client's) remote_write configuration at that pipeline endpoint, adjusting the uri parameter if it was customized away from the default /api/prom/push.
3. Enable tag_from_uri if ingested metrics should be tagged based on the URI path segment they arrived on.
4. Configure TLS options (tls, tls.verify, tls.ca_file, tls.crt_file, tls.key_file) if the pipeline needs to terminate TLS for incoming remote-write traffic.
5. Tune buffer_chunk_size, buffer_max_size, and mem_buf_limit if bursts of remote-write traffic need to be buffered without dropping records.
