Updated operator-sdk to v0.4.1

[jpkrohling]

I'm currently facing a problem with the fakeClient when working on #193, which is solved in newer versions of the controller-runtime library. As the operator-sdk also depends on that library, I'm bumping the operator-sdk to 0.4.1, which brings the controller-runtime 0.1.8.

The e2e tests for this PR are passing:
