Add a design.md document

[chiaradiamarcelo]

It would be nice to include a design.md document or something similar to describe the design, distribution, interaction, implementation, where-to-find, hows-and-whys, etc of the components of the TDVT.
At the moment I find it quite hard to understand how everything works together, and by this I find it really hard to collaborate to the project.
One small example, it's not easy to find tests, and determine how they are chosen and executed, and what does it mean if some tests pass and some fail (e.g, I noticed there are many vendor folders that contain tests, at first glance specifically for those vendor folders. Does this mean that all those tests are executed against a connector when running the TDVT? Does this mean that for a new connector a new vendor folder should be added? What does it mean if for a new connector, eg, the tests for PostgreSQL succeed but the ones from Oracle fail?).

Describe the solution you'd like
A clear design document that would allow external contributors to understand and collaborate with the project.
