Remove hard coded values from dpsim-api + dpsim-worker example

[m-mirz]

Network files should be stored in sogno file server and the simulation request needs to include the fileID.

• [x] translate file ID to URL in S3 storage using sogno file service ID
• [x] request to dpsim API with file ID (zip of CIM files)
• [x] create job description and send via AMQP to be retrieved by dpsim worker
