Description
This api is no longer provisional in 3.10 and this reduces the number of dependencies for any instrumented code on >= 3.10
See the official docs
This was suggested in #3234 but never implemented.
Fixes #3234
and avoids issues such as #3333 on those versions in the future.
In my opinion it's a really nice feature of opentelemetry (compared to opencensus) that the api only has
very light dependencies. Currently it has 5 dependencies. Of these one is setuptools which can be dropped (#3372)
and 2 are importlib-metadata and iss dependency zipp. Both or these are std lib backports so with these changes they
are dropped.
(The remaining dependencies are Deprecated and its dependency wrapt)
