Summary

• Following the updates for packages for security. We need to drop support for old python versions, as they have reached their end of life, future security updates will not be done for these versions. And packages updates can broke DDS for old python versions. -> https://devguide.python.org/versions/

• This update also means updating Pylint, as the support for the new python versions is not included in 2.X.X

• Bumping pylint implied new rules that we need to adapt the code. From this new rules, there is one that limits to 5 the number of arguments in a function. We need to disable it as it will mean heavy code changes.

@rv0lt There should only be one label. Either type: docs or type: dependency

I'm pretty sure there are things in the workflows that we need to change? E.g. that we have a pylint for these Python versions I believe

[rv0lt]

back to draft until the pylint issue is fix

I am not sure which label would fit this case @i-oden
