This integration test allows us to detect if a given feature gate will panic kubeadm. This builds on the assumption that a golang panic makes the process exit with the code 2. These tests are not trying to check if the init process succeeds or not, their only purpose is to ensure that the exit code of the `kubeadm init` invocation is not 2, thus, reflecting a golang panic. Some refactors had to be made to the test code, so we return the exit code along with stdout and stderr.
