##### SUMMARY
The documentation states that all our returned resource ids are
integers, this change aligns our modules with the docs.
The impact of this change should be minimal, as ids are used for
identification purposes by directly forwarding the values (no
transformation of the data is done).
##### ISSUE TYPE
- Bugfix Pull Request
##### COMPONENT NAME
All modules
##### SUMMARY
Since we only support python >=3.8, the `to_native` python2/3
compatibility function is not needed anymore. We only keep it for
printing a traceback free exception message. Where a type conversion is
needed, we use the built-in `str()` function.
