Add back the OpenCensus bridge code

[MrAlias]

Blocked by the metric SDK having a working example in the new_sdk/main branch

Removed in https://github.com/open-telemetry/opentelemetry-go/pull/2802

Is this still blocked?

I'm actually looking to export OTel traces from a component that's instrumented with the OpenCensus SDK. Would bringing back the tracing bridge code be an option so we don't wait on the metrics SDK?

This bridge was never removed from the main branch and continues to be a part of the releases. It is removed on the new_sdk/main branch as we are reworking the metric SDK. The current release should still work to bridge tracing functionality.

oh great - thanks for the clarification

I'm working on spec PR to specify how the OpenCensus bridge will be implemented: https://github.com/open-telemetry/opentelemetry-specification/pull/2722

Moving to the next milestone (Metric SDK Beta) based on discussion in the SIG today.

If https://github.com/open-telemetry/opentelemetry-specification/pull/2722 is resolved before the alpha release, we will move this back into the alpha milestone.

We have a replacement bridge.
