Fixed the following golint warnigns:
- package_validator.go:68:1: receiver name should not be an underscore, omit the name if it is unused
- package_validator.go:89:1: receiver name should be a reflection of its identity; don't use generic names such as "this" or "self"
- package_validator.go:96:1: receiver name should be a reflection of its identity; don't use generic names such as "this" or "self"
- package_validator.go:119:1: receiver name should be a reflection of its identity; don't use generic names such as "this" or "self"
- Move from the old github.com/golang/glog to k8s.io/klog
- klog as explicit InitFlags() so we add them as necessary
- we update the other repositories that we vendor that made a similar
change from glog to klog
* github.com/kubernetes/repo-infra
* k8s.io/gengo/
* k8s.io/kube-openapi/
* github.com/google/cadvisor
- Entirely remove all references to glog
- Fix some tests by explicit InitFlags in their init() methods
