OpenTelemetry context API is broken

[yann-combarnous]

Summary of problem

Trying to import from ddtrace.opentelemetry import TracerProvider and getting the following error:

ImportError: cannot import name 'TracerProvider' from partially initialized module 'ddtrace.opentelemetry' (most likely due to a circular import)

Seems similar to #9917

Hey @yann-combarnous,

Thanks opening this issue. I am able to reproduce this error with ddtrace<2.8.7 but not in more recent versions of the library. This fix might be missing an edge case. I was wondering if you could modify the reproduction below to use v2.12.2 (or provide a sample app) this will help us narrow down the issue.

Reproduction

1. python3.10 -m venv .v && source .v/bin/activate
2. pip install ddtrace==2.8.6 opentelemetry-api==1.27.0
3. DD_TRACE_OTEL_ENABLED=true python -c "from ddtrace.opentelemetry import TracerProvider"
