Tracing: Migrate Google Cloud (Stackdriver) client to OpenTelemetry (#…

…4838)

* Add migration utilities

- Add method to create bridge tracer
- Implement a sampler which enables us to force tracing

Signed-off-by: Matej Gera <matejgera@gmail.com>

* Migrate and rename Stackdriver to Google Cloud

- Rename to Google Cloud, keep it backwards compatible
- Refactor and move to OTEL exporter
- Adjust factory to use bridge tracer for this provider

Signed-off-by: Matej Gera <matejgera@gmail.com>

* Adjust HTTP middleware

- to ensure force tracing / populate trace ID header works for the bridge tracer as well

* Update documentation

* Copyright file headers

* Fix doc formatting

* Upgrade OTEL to 1.3.0

Signed-off-by: Matej Gera <matejgera@gmail.com>

* Wrap bridge tracer to make propagation work

- Currently, bridge tracer supports only HTTP headers as a carrier.However, our instrumentation e.g. for gRPC uses metatada.MD as a carrier instead, breaking the propagatin. This fix works around it by 'converting' the carrier to HTTP header. See code docs for details.
