Description

This feature will provide a register-api for ELN-admin-user to register devices.

The API will provide:

• the id/name of a newly registered/cerated device
• An JWT with the information of the device included

In the interest of safety, a further property has been added to the device models. This property "is_super_device" allows devices to register new devices. In addition an API was implemented in which you can create new devices.
