Implement JSON:API

[s3bsch]

Adapt the prototype to provide a JSON:API following best practises and provide the following actions:

• List robots
• Show robot
• Update robot name
• Show order
• Show robot with orders
• Add order for robot
• Update specific order

Further I would like to structure the files in a domain driven way.
