Migrate rule instances to new table structure

[dmjb]

Please describe the enhancement

Rule instances are currently stored as a list of JSON objects which makes querying challenging. Migrate rules over to a dedicated table structure.

Solution Proposal

1. Define new table
2. Write rule instances to old and new tables
3. Migrate old rule instances to new table
4. Change business logic to use new tables exclusively
