merge: Add PatternFly 4 web interface (#161)

This pull requests adds the new web interface based on the PatternFly 4 design framework.
This framework enables us to develop more quickly the interfaces necessary in OpenDC. 

* Remove the OpenDC landing page from the web interface module
* Add support for the PatternFly 4 framework in Next.js
* Relax topology schema requirements
* Migrate UI components to PatternFly 4
