Browse Source 
* refactor: switch from opencensus to opentelemetry

* tempo works as designed nooooot

* fix: log traceids

* with grafana agent

* fix: http tracing

* fix: cleanup files

* chore: remove todo

* fix: bad test

* fix: ignore methods in grpc interceptors

* fix: remove test log

* clean up

* typo

* fix(config): configure tracing endpoint

* fix(span): add error id to span
