Implement repo API and contracts

• Define auto dependency flow repo API #183 Auto-dependency flow build
• Patch-less build

Is there a document that covers the repo API in some detail? I know some of the motivation behind it - basically document/automate inputs (files, build commands) and outputs (artifacts) of each repository - but is there some place where I can read up on more details?

@omajid what you are describing will be part of this issue, viz. @eerhardt will take stock of what we need and design the API for repos.
