Introducing Lerna as mono-repo manager (#763)

The internal structure for the JS driver started to be a bit complex to maintain and realise what's the boundaries between packages.

Introducing Lerna helps to keep the repository tidy and easy to build.

- Moving packages to a separated folder
- Fix the build process and testkit
- Automate build with lerna
- Update Readme.md with the build instructions and package information.
