[TECH DEBT]: Consistently use the DependencyGraphContext

[JCZuurmond]

Is there an existing issue for this?

• I have searched the existing issues

Problem statement

The DependencyGraphContext is not used consistently

Proposed Solution

Consistently use the DependencyGraphContext where applicable:

1. DependencyGraph.__init__
2. WorkflowLinter.__init__
3. LocalCodeLinter.__init__
4. Check for other locations when starting working on this issue

Also:

• Add docstring for the class and its attributes
• Maybe move the context to the contexts.py module

I think the inconsistent usage arose when the context was introduced but not applied everywhere.
