feat(tvix/store): add opentelemetry r/7308

This is behind the otlp feature flag (currently enabled by default).

By default, this will try to push traces to a OTLP collector running at
https://localhost:4317.

You can make one available by running:

```
docker run -d --name jaeger \
  -e COLLECTOR_ZIPKIN_HOST_PORT=:9411 \
  -e COLLECTOR_OTLP_ENABLED=true \
  -p 6831:6831/udp \
  -p 6832:6832/udp \
  -p 5778:5778 \
  -p 16686:16686 \
  -p 4317:4317 \
  -p 4318:4318 \
  -p 14250:14250 \
  -p 14268:14268 \
  -p 14269:14269 \
  -p 9411:9411 --rm \
  jaegertracing/all-in-one:1.42
```

Started like that, jaeger brings a web interface at
http://localhost:16686/search

As documented in
https://docs.rs/opentelemetry-otlp/latest/opentelemetry_otlp/, you can
point this to another location by setting `OTEL_EXPORTER_OTLP_ENDPOINT`.
