Traces: Enable showing trace ids

[gabor]

this feature was behind the experimental showTraceId feature flag until now, now we are removing the feature toggle and enabling it by default.

how to test:
to have grafana-backend generatea traceids, add something like this to the grafana config file:

[tracing.opentelemetry.jaeger]
address = http://localhost:1234
propagation = jaeger

note, nothing has to run at the specified address (localhost:1234) in this case, to be able to test the change.

1. run a query that does not fail, like a loki query or prometheus query. after you run it, open the query inspector, go to the stats-tab, scroll to the bottom, and verify that the traceId is shown there.
2. run a query, for example a loki or prometheus query, and make a syntax error in it. for example this loki query : {a="42"} haha
   • verify that the traceid is added to the end of the arriving error message
   • go to the query inspector's error tab, and verify that you can see the traceid at the end of the error message here too.
   • go to the query inspector's stats tab, scroll to the bottom, and verify that you can see the traceid here too.
