WIP: Move measurement to service layer
This MR will push the measurements down from the rake layer to the service layer (where the actual import/export logic executes).
This means we'd be able to take measurements via our performance CI pipeline, which is currently based on API integration, not rake tasks. Since we will use a structured JSON log instead of logging plain text to stdout, these logs could be indexed by Kibana...
