Fix flaky serverless integration test

[thedavl]

What does this PR do?

fix flaky serverless mini agent integration test

It seems like the previous way we were invoking the integration test gcloud function (using a known url prefix and just appending the function name) did not reliably invoke the function. It would sometimes return 404s.

This PR changes the test to capture the output from the function deploy command, extract the function url from the output, and invoke the function using it.
