Description

We still had some code in place for backwards compatibility that should be removed in 0.18.0.

Development notes

• Removed code in kedro.framework.project._init_.py there for backwards compatibility with projects that don't have the pipeline_registry.py file.
• Removed configure_project(package_name) on session creation.

So much for this being a simple 1 point ticket 😬 Great job getting through it!

Just two small suggestions, not important:

1. If _ProjectPipelines.configure is usually called with pipelines_module = None then it might be worth giving it a default value of None so those calls don't have to specify None explicitly (which looks very slightly unnatural to me).
2. Maybe __init__ should also call self.configure just to reduce repetition and make it clear it's doing the same thing.

I've addressed point 1, but for point 2 it seems weird to not define the class attributes in __init__, and actually my IDE complains about that as well if I make the change.
