ADR: Create a mono repository

[Sander3003]

[TODO: convert it into an ADR]

Use https://lerna.js.org/ (or others) to create 1 repository for components

Motivations to do so:
one code owner to rule them all
One storybook for easy checking/testing components
1 NPM token
Easy copying
Lower workload on the developers
1 ESlint

Disadvantages:
1 maintainers for all compontents (mitigation: can be splitup in multiple mono repositories to make it manageble)
Risk of overlapping (migitation: can be enforced by Lerna)
