Thanks! Have other operators removed the use of glog yet? If not, would this break existing 3rd party logging service by using different logging frameworks?

@terrytangyuan Tf-operator and mpi-operator still has few references. I will file follow up PRs to migrate them either to klog or logrus later. This will not break existing logging service. The situation is we have multiple logs solutions and this PR helps to use unified one across the project. (In this project, logrus)

Fix an edge case in the test and please have another look.
