usagestats: Add Amplitude IDs into BigQuery events
Created by: attfarhan
Adds DeviceID, EventID, and InsertID to events sent to BigQuery. These IDs are used to identify events in Amplitude. In the case that we have issues with Amplitude that cause events not to be sent directly from our Cloud app, we will use BigQuery as a backup. Therefore, we'll need these IDs to ensure we are filling in data correctly, and we have the fields required by Amplitude.
Also updates the eventID format to include the event type and some additional formatting.
