[SDG] Add Pydantic Support #930
Description
Is your feature request related to a problem? Please describe
Currently, SDG before OSB 2.0 release, has minimum ways of ensuring that the yaml provided adheres to a schema that SDG expects.
Minor defects in sdg-config.yml that the user provides can cause issues for developers and make it difficult to debug.
Describe the solution you'd like
We should incorporate a well-backed library like Pydantic that can ensure strong data validation while preserving the current architecture. This should be a simple swap in and replace.
By doing this, we'll make SDG more robust, have better error handling, and better extensibility for future config changes.
