Description
We started seeing mypy test failures in loader.py after the upgrade to 0.750 in #258.
% mypy --namespace-packages opentelemetry-api/src/opentelemetry/util/loader.py
opentelemetry-api/src/opentelemetry/util/loader.py:181: error: Incompatible types in assignment (expression has type "Callable[[Type[_T]], Optional[object]]", variable has type "Optional[Callable[[Type[object]], Optional[object]]]")
Found 1 error in 1 file (checked 1 source file)
I pinned the mypy version in 792449e as a temporary fix, but we need to update the annotations to work with latest.
