UpdateProcessing missing steps

[StefanoSperetta]

Missing steps for the UpdateProcessing branch:

• start the scheduler once when the server starts to limit the risk of double initialization
• remove XTCEParsers creation in scheduler
• fix unit tests related to processing
• create dummy influxDB server for testing
• create dummy satellite processor for unit tests
• check if frame belongs to stream in raw frmes processor, rather than checking if frames is correct. This should make sure all frames from a satellite (even if no specific frame is described in telemetry) are moved to the raw bucket
• delete processed frames
• figure out if all frames in buffer make it to the raw bucket
