Update old format message files

[nicolemah99]

We need to update the renaming script to also update the message file format. We no longer need the path because the mqtt service is now on the DAS side and the script that reads the message should determine the path to use itself since the message is being transferred with the file. Additionally, we need to update the field names and include the md5sum of the zip file in the message.

Old message file format

{
  "id": "10009",
  "filename": "10009.zip",
  "path": "kea/events/2024-06/sel00",
  "data_type": "events"
}

Current message file format

{
  "event_id": "10009",
  "filename": "kea-events-sel00-202406-10009.zip",
  "path": "kea/events/level0/2024-06/sel00",
  "data_type": "events"
}

New message file format

{
  "event_id": "10009",
  "filename": "kea-events-sel00-202406-10009.zip",
  "md5sum": "d41d8cd98f00b204e9800998ecf8427e",
  "data_type": "events"
}

Required Updates:

1. Remove Path Field:
   • The script that reads the message should determine the path.
2. Field Names:
   • Change id to event_id.
   • Update filename to the new zipfile name kea-events-sel00-202406-10009.zip
3. Add md5sum Field:
   • Include the MD5 checksum of the zip file.
