Remove cmd/integration test

Fix #24440

After few cleanup PRs:
https://github.com/kubernetes/kubernetes/pull/27182
https://github.com/kubernetes/kubernetes/pull/27535
https://github.com/kubernetes/kubernetes/pull/26016

The only things that are being tested here is:
- starting master components without any verification (so if it didn't start, it will still work :P)
- checking if kubelet is starting containers from http manifest.

The latter is already tested in:
https://github.com/kubernetes/kubernetes/blob/master/pkg/kubelet/config/http_test.go#L54

So the test is now useless, at the same time, significantly increasing time spent on integration tests.
