otlphttp input rejects protobuf

[mdaniel]

The cited OTLP log ingest does not work with modern OTLP collectors, neither in otlphttp nor oltp mode:

Given:

  exporters:
    otlphttp:
      endpoint: http://qryn.qryn.svc:3100
      tls:
        insecure: false
  service:
    extensions: [health_check]
    pipelines:
      logs:
        receivers: [ filelog, otlp ]
        processors: [batch]
        # exporters: [ otlp ]
        exporters: [ otlphttp ]

then the collector gets back a 500
