Refactor the pipeline to output multiple reason codes

[jeancochrane]

Currently, the sales val pipeline outputs reason codes for each flag that combine a characteristic reason with a price reason. For example, Family sale (high) is a combination of a characteristic reason (family sale) with a price reason (high price).

Per the updated sales val design doc, we need to refactor the pipeline so that it outputs multiple reason codes for each flag. This requires us to disaggregate our characteristic reasons from our price reasons, and update the pipeline to output one characteristic reason and one price reason for each flagged sale.

This is what the refactored set of reason codes should look like:

• Characteristic reasons
  • Short-term owner
  • PTAX-203 Exclusion
  • Family sale
  • Non-person sale
  • Statistical Anomaly
  • Price swing / Home Flip
• Price reasons
  • High price
  • High price per square foot
  • Low price
  • Low price per square foot
