chameleon/ui: Create a boilerplate app for Chameleon Control Center

[Why]
We need a UI to start developing our control center that will manipulate
Chameleon from a nice UI.

[How]
1. The code lives in dev/contrib repo.
2. It can be developed on the local workstation as it requires node
   (only for development)
3. It's been modified that a production build will be static files.

To run: `npm start`
To build: `npm run build`  and the output in build/directory.
