[KED-1169] Library code should be framework decision agnostic

Description

This line in library code makes assumptions about the user code (i.e. that the directory src exists). This used to be in kedro_cli.py where all “frameworky” decisions are made, but now it is hidden (and undocumented), and the user is no longer able to change it.

Context

Working on a project where src does not exist - I would like to modify the python path myself (or at least have control over what gets added or not)

I understand that this is probably there to make this work both in jupyter/ipython and when running cli commands - however assumptions about user code should not be in library code.

We have made the source directory configurable with source_dir key in .kedor.yml in https://github.com/quantumblacklabs/kedro/commit/8de924819ae7e622a5a73b00f742e77efb936438 so you can customise it like

source_dir: .

Or

source_dir: src/nested/

if src doesn’t suit your use case.

It will be released in the next release, so I’m closing this issue, but do let us know if you have any questions/comments. We are still continuing on the framework redesign, so more refactoring is coming soon 😃

@philippegr Thank you for raising this! As @idanov mentioned above, our architecture change in framework code is in our plan in the first quarter of this year, mainly improving the usability of KedroContext (and load_context etc). Hopefully we will be able to release it at the next major releases in near future 😃
