Implement Jaeger gRPC remote storage writer interface

[arajkumar]

Sub tasks

• Translate Jaeger model.Span to Otel ptrace.Traces
• Write E2E test
• Update documentation

Implements #1535.

Testing

Note: This testing strategy establishes a cyclic dependency, where the promscale exports it's internal tracing data to Jaeger collector and which would again pushes back to gRPC stroage implementation which is again promscale.

# shell 1
$ ./dist/promscale --db.name promscale --db.password promscale --db.user promscale --db.ssl-mode allow --startup.install-extensions --startup.upgrade-prerelease-extensions -telemetry.trace.jaeger-endpoint http://localhost:14268/api/traces

# shell 2
$ docker run -it -e SPAN_STORAGE_TYPE=grpc-plugin -p 14268:14268 jaegertracing/jaeger-collector:1.36 --grpc-storage.server=host.docker.internal:9202

Description

This is added to skip creation of Jaeger store when doing promql_endpoint_integration_test.go

Overall looks good. My only concern is keeping translation part out of Ingestor.
