OpenTelemetry Traces for Enterprise

## Feature Description

Hasura has instrumented all API queries, mutations and subscriptions with the [OpenTelemetry](https://opentelemetry.io/docs/concepts/signals/traces/) format. These traces can be exported directly from your Hasura instances to your observability tool that supports OpenTelemetry traces

## User value / outcome

Traces can be used to identify where performance bottlenecks are happening. Trace propagation can be used to track the journey of a request from your application to Hasura and to other services.

## Current status (design, alpha, beta etc.)

Beta, available from `v2.18.0`
