Include Adyen packages recursively

[allburov]

Description
Right now if we try to install the library from develop branch it gives a error

ModuleNotFoundError: No module named 'Adyen.services'

It happens because the services module is used to be file and now it has been split to a module and the setuptools don't include all modules recursively, so we have to "find modules" this way.

Tested scenarios

# install the library
git clone https://github.com/Adyen/adyen-python-api-library.git
cd adyen-python-api-library
python ./setup.py

# try to import and use it
echo "import Adyen" > test.py
python test.py
>>> ModuleNotFoundError: No module named 'Adyen.services'

Hi @allburov, could you please try to run
python ./setup.py install
as this should properly install the package, and let you experiment with our develop branch.

@antolo-arch good suggestion, but we want to use it in the project requirements.txt, because I'd like to use a few unreleased features (even if they contain bugs, it's fine for us, we're going to test it properly before).
pip install (or poetry install) in my case works with build, not install.

I think it's kinda like a good practice for python projects - be able to be installed from git via pip install git+https://github.com/...

@antolo-arch
Sorry for confusing, I got that I haven't highlighted it in the description.

This is the case:

# Install
poetry add git+https://github.com/allburov/adyen-python-api-library.git#develop
poetry install

# try to import and use it
echo "import Adyen" > test.py
python test.py
>>> ModuleNotFoundError: No module named 'Adyen.services'

Also without the change you'll encounter problems with publishing the package to pypi - in the current state I believe it won't contain services directory

Hey @allburov,
I see, you're right, the service directory was missing indeed. Thanks for the contribution! 🚀

@antolo-arch thank you for such quick reaction! ❤️
