infra v2: migrate vehicletraffic-bluetooth

[clezag]

Summary

Google spreadsheet to get station list ( implementation with trigger like spreadsheet data collectors)
REST endpoint (PUSH)

• POST /json consumes list of bluetooth records and pushes them to ODH + updates stations
• GET /json?station-id=xxx get date of last record for given station
• POST /hash consumes list of bluetooth records and returns a list of MD5 hashes of the MAC addresses

Migration strategy

Data collectors

• Custom REST endpoint
  • Directly respond to /hash and GET /json requests
  • Implement POST /json, or consider proxying to generic REST ingress, adding parameters
• Shared spreadsheet data collector

Transformer

• Single transformer with two queues
• Data/Station from REST endpoint, getting up to date station data from ninja
• Station sync from spreadsheet
