Version or schema aware db seed script

[andrew-jameson]

Description:
Suggested this feature to be out-of-scope on #2965, will implement separately. Goal of this will be to enhance seed_db to be schema-aware and perhaps to build out a catalog of version::schema for future testing and development.

Acceptance Criteria:

• Utility must be able to differentiate between versions of TDP
• seed_db command must adapt certain fields to older versions
• Testing Checklist has been run and all tests pass
• README is updated, if necessary

Tasks:

• Implement version/schema-tracking mechanism (we should be able to use django's migration table)
• Tie above into seed_db command
• Parameterize seed_db::validValues with version/schema notation to affect outcome
• Run Testing Checklist and confirm all tests pass

Notes:

• Update indicator validation was recently changed, that might be a good first MVP.

Supporting Documentation:

Open Questions:

• What is priority and/or value-add of this in relation to beyond 4.0 API submissions?
• Can this be tied into integration testing via cypress?
