Describe the bug

It's missing some configuration for jaegerremote and traces are not being sent.

		jaegerRemoteSampler := jaegerremote.New(
			"jaegerremote",
			jaegerremote.WithSamplingServerURL(samplingServerURL),
		)

Reproducing the bug

1. Use a docker-compose to run jaeger https://github.com/jaegertracing/jaeger/blob/main/examples/hotrod/docker-compose.yml
2. Clone repo https://github.com/ory/oathkeeper and use master branch
3. Add tracing with sampling to your configuration:

tracing:
  service_name: ory-oathkeeper
  provider: jaeger
  providers:
    jaeger:
      sampling:
        type: const
        server_url: http://127.0.0.1:5778/sampling
      local_agent_address: 127.0.0.1:6831

4. Execute some curls to oathkeeper as proxy
5. Check traces on jaeger
