pkg_resources is deprecated and removed in Python 3.12

The problem

I was trying to set-up a development environment for LibreNMS. I was using pyenv to install python 3.13 and noticed that after running composer install command I was getting error from post install script.

> scripts/dynamic_check_requirements.py || pip3 install --user -r requirements.txt || :
Traceback (most recent call last):
  File "/home/dot-mike/code/librenms/scripts/dynamic_check_requirements.py", line 12, in <module>
    import pkg_resources
ModuleNotFoundError: No module named 'pkg_resources'

Turns out that pkg_resources is deprecated https://setuptools.pypa.io/en/latest/pkg_resources.html

Use of pkg_resources is deprecated in favor of importlib.resources, importlib.metadata and their backports (importlib_resources, importlib_metadata). Some useful APIs are also provided by packaging (e.g. requirements and version parsing). Users should refrain from new usage of pkg_resources and should work to port to importlib-based solutions.

setuptools that includes this module was removed as per default in 3.12 https://docs.python.org/3/whatsnew/3.12.html Although the docs do specify python3-setuptools as part of the installation command.

the dynamic_check_requirements.py script should move to use importlib instead.

What was the last working version of LibreNMS?

No response

Anything in the logs that might be useful for us?

I'm not sure what the supported versions of python3 are ... but I guess we will get bitten by this at some stage.

I'm also not sure why we do a check to see if modules are satisfied and only if that fails we run the pip install -r requirements.txt .... sort of seems like we could just run it anyway regardless and save a bunch of additional foo?

Anyway will throw an updated script and see how that works for people.
