How jx 3.x is built

We are trying to take a microservices approach to creating improvements to Jenkins X with 3.x.

We are trying to keep 2.x of Jenkins X stable; but provide a place where we can rapidly innovate on 3.x.

So the main jx CLI tool for 3.x is defined at jenkins-x/jx-cli which is a small core using lots of separate plugin binaries, components and libraries which allows us to go faster improving 3.x, refactoring code, improving quality and code coverage while removing technical debt - without needing to touch 2.x.
