- Add integration test for serving cert auto-generation and rotation
- Add unit test for `WithInitialEvent` of the cert manager controller
- Move UpdateAPIService() into the `apicerts` package, since that is
the only user of the function.
Instead, make the integration tests a separate module. You can't run
these tests by accident because they will not run at all when you
`go test` from the top-level directory. You will need to `cd test`
before using `go test` in order to run the integration tests.
