New data model

[sereprz]

The current data model doesn't support all campaign use cases, e.g. some campaigns allow riders to pick their delivery date/time, or have items that can be split between multiple riders/tasks. To accommodate these use case we're implementing a new data model with more flexibility around the parameters of a campaign/task

In broad strokes:

• create new tables:
  • supply
  • demand
  • point of contact
• backfill historical data into the new tables
