Right now the GET /v1/connectors/{connector_id} API call returns when a connector was:

- created ("created_at")

-last succeed ("succeeded_at")

- last failed ("failed_at")

In order to make some coherent improvements to the Airflow "Fivetran Provider Async" package, I need a timestamp indicating when a sync was last started. The idea is, when a sync was last started is an indicator for what data is being synced. If a sync starts at 3:05 and ends at 3:15, all the data up to 3:05 should be synced but not necessarily the data that arrived between 3:05 and 3:15. Therefore, 3:05 is the timestamp I would ideally like to use as an indicator for what data is being included in the sync.
