Fix the e2e K8s test (#1842)

* Debugging the integration testing.

It seems to be consistently failing (also fix a typo in the file/leg name).

I'm disabling `-v` for `go test` because it interleaves the test output in ways that make it painful to read a single failing test's output when `t.Parallel` is involved.

* Try swapping registry:2 for the registry add-on

* Drop logf and make Logger private
