Introduce smart graph generator for monorepo package dependency and affected packages on commit and PR

[GAndanje]

It is desirous to have a graphical representation of projects within the monorepo.
As the monorepo scales it would be crucial have an easy and trusted way to tell the relationships that exist between your packages.
This will help optimize builds by leveraging caching in CI to only run tests against packages affected by PR or commit.
Beside in rare cases it will help break any dependency cycles.
The goal is to achieve something similar to what Nx offers and other monorepo managers
