SDC-1590 Count dataproducts
- dataproducts are counted based on what is in 'outputs.ingest' and stored in a task.nr_of_dps
- the same is done for the activity (SAS_ID level) and stored in activity.nr_of_dps
values are available through the REST API, the activity,nr_of_dps can be used by the ingest service to write that value to the LTA
