Implementation of a service to take registration requests

[constantinius]

This service shall have two routes:

• User information: when called with user credentials encoded in a JWT, this endpoint shall return the Object Storage endpoint, bucket (or container name) and path the processor can place its files. As the integration with the PEP/PDP (user authorization) is not yet understood, this needs to be mocked to a single bucket + path prefix.
• Registration: this route shall take the prefix of data to be registered into the data-access component. Again, the users credentials are passed via a JWT. The path shall be placed into the redis registration_queue of the VS

This service shall be implemented by the means of any Python web framework (suggestion: Flask).
