Add integration tests for end to end flow for data checks --> data check actions

[angela97lin]

There are currently unit tests for both data checks and data check actions, but there's no test that takes the output of a data check and passes it to the code for data check actions. This has caused some issues with API consistency, found and written about in #2792. It could be good to create an end-to-end test flow that runs data checks, and feeds the output of validate to creating data check actions components.

This issue tracks adding integration tests (subfolder of tests) and creating a separate job for integration test suites?

Note: The immediate goal of this issue to define data check integration tests, but a secondary goal is to put in place a pattern for our more heavy lifting tests. :)
