Payload-tracker normally has a 5+ million kafka lag.

As a first step to work towards improving this, I think we should modify PT to use bulk inserts.  Locally, buik inserts cuts the insertion time of 10,000 records in half.

I think we should make a new implemntation of the InsertPayloadStatus() method which uses a configurable batch size.  We should also make it possible to switch between the 2 implementations (bulk, non-bulk).

I would start out with a batch size of 10 as the default and go from there depending on how it goes.
