Replace Lerna with Nx

[silentHoo]

Refactor Request

Things grew up over time are now more complex compared to when we started some years ago. Time to think about what needs to have a change. One thing we heavily rely on is our monorepo. We organize the packages for the core components, the Angular and React wrappers as well as the landing page and storybook as own packages.

Lerna is a good tool and focused on linking multiple packages. It helps use publihsing to npm. But that's it. Nx on the other hand is all about development workflow.

Therefor we replace Lerna with Nx. See also https://blog.nrwl.io/why-you-should-switch-from-lerna-to-nx-463bcaf6821.
