[SPIKE] Integration Tests for Stanford and Cornell DAGs

[jermnelson]

Investigate and recommend a strategy for DAG integration tests.

Possible strategies:

• Use airflow command-line operations to run Dag with a mocked sqlite database and external APIs calls
• Use Cypress and docker compose that provisions and runs DAGs with mocked external APIS

Perhaps I'm not understanding your goals here, but why don't we just run an end-to-end test on staging? That seems far simpler than doing an automated provisioning of all components + mocks.

@jcoyne, agreed. Using our Stage environment would be a better for our integration testing.
