Restructure Project

To make it easier to have separate implementations, we have
structured the repo so that there are three Bazel workspaces:

  - The API (and reference)
  - The vendor implementation for dev
  - The vendor implementation for prod

This allows the vendor implementation to be separated from
the API, while it makes little difference in this repo. While
it makes little difference for this repo, it makes managing versions
much easier internally. We do it here to better reflect our internal
structure to partners.

A vendor implementation has been stubbed in (BUILD file and directory
structure) to provide vendors with some scaffolding to organize their
implementation.
