build: Move dependencies to `requirements*.txt` files
State: closed | Pull request: yes
Labels: name: Run CICD

# What does this PR do ?

This PR pushes dependencies from Dockerfile to down to requirements files. This is done for all dependencies except of Apex, because Apex stricly requires `--no-build-isolation`. This is a bad practice and not required for other dependencies, so I decided to separate it.

What's missing to this PR are two extensions:

1. During/after split of release branch, we replace git-dependencies with pypi-dependencies (and version for that specific release)
2. Before pushing to pypi, we comment out/delete all git-dependencies

Mitigation guide:

* Add sensible and useful docstrings to functions and methods
* For trivial methods like getter/setters, consider adding `# pylint: disable=C0116` inside the function itself
* To disable multiple functions/methods at once, put a `# pylint: disable=C0116` before the first and a `# pylint: enable=C0116` after the last.

By applying these rules, we reduce the occurance of this message in future.
