Remote sampling

[manojm321]

Hello, I'm trying to move away from jaeger-agent completely. I can export jaeger traces via otel-collector, but not finding a way to support remote sampling.

Here is an example of strategies defined in jaeger-collector.

          {
            "service_strategies": [
            ....
            ],
            "default_strategy": {
              "type": "probabilistic",
              "param": 1.0,
              "operation_strategies": [
                {
                  "operation": "/health",
                  "type": "probabilistic",
                  "param": 0.0
                },
                {
                  "operation": "/metrics",
                  "type": "probabilistic",
                  "param": 0.0
                }
              ]
            }
          }

I came across a few github issues but none of them concluded.

For now I'm settling for - run both jaeger-agent and otel-collector. jaeger-agent to only server sampling, since sampling decisions is taken by jaeger SDK anyway.

otel-col will collect and push traces as needed.
