[Data Discovery] Run API integration tests in Serverless

[davismcphee]

Summary

This PR copies the Data Discovery API integration tests to test_serverless. They are currently in the common folder and will run once for each project type in CI, but we could instead move them to a specific project if we don't want to run them three times each.

In the future these should run as deployment-agnostic tests, but support does not yet exist (see #161574), so in the meantime they've been duplicated and modified in place. I've left TODO comments where test files have been modified so we know what needs to be addressed once they are converted to deployment-agnostic tests.

Part of #162347.

Dear @davismcphee , I thought you would print this code and send it to me? Neithertheless, looks good to me, so much LOC++
Cheers,

PS a follow up issue to track the deduplication like suggested in the other PR sounds like a good idea, although I might complain about the reduced net worth of our code base then
