`_arrange_cols` makes it so that user can specify whether they want a plural ID or a singular ID - needed?

This is confusing behavior, specifically with the get_monitoring_locations() function. The service is called "monitoring-locations", but the decision was made to return the "id" column as "monitoring_location_id", NOT "monitoring_locationS_id". However, the behavior is as follows:

• someone could request to have the "id" column returned. In this case, the column returned is named "monitoring_location_id"
• someone could not specify properties at all. In this case, the column returned is named "monitoring_location_id"
• someone could notice the pattern that the "id" columns are renamed to service + "_id" and request to have the "monitoring_locations_id" returned. In this case, the column returned is named "monitoring_locations_id".

Is this a necessary offering? I'm not sure.
