ETL Sanger Numbers to Donor Aggregation Index

[rosibaj]

• Create the query to the RDPC for sanger-analyses (behind feature flag)
• Transform data to donor centric view
  --- new step in transform to count unique T/N pairs
• Fill in the donor mapping with RDPC data that was transformed (for sanger only)

Take the query from the the RDPC and transform the data into the needed shape

Expected Outcome

• Can query for the numbers from the API for sanger-analyses
  
• Has a feature flag to TURN OFF for production deploy
