go test ./... may break the current cluster set on kubeconfig

Bug Report

What did you do?

After the project bootstrap using operator-sdk, the directory test/e2e is created, if you run a go test ./... you may lose cert-manager and prometheus-operator on the current cluster set on kubeconfig.

What did you expect to see?

I think that is a accident, but we might prevent similar situations from happening to others. go test ./... should not trigger the e2e tests, we should use a environment variable to trigger e2e tests just on Makefile

The same happend to us today. We deleted cert-manager and prometheus on two clusters. This is really dangerous. It would be great, if you would set the k8s-context in the Makefile or in the test itself to something like operator-kind and not simply using users current k8s-context.
