- 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
Change-Id: I92db545ff36fcec83afe98f550c9e630098b3135
Loop over priorityConfigs seperately. The node loop can only safely
modify result[i][index]. Before this change it sometimes modified
result[i] concurrently with other loops.

This previously caused a panic when moving lastKnownGood between two
non-nil values, because we were comparing the interface wrapper instead
of comparing the NodeConfigSources. The case of moving from one non-nil
lastKnownGood config to another doesn't appear to be tested by the e2e
node tests. I added a unit test and an e2e node test to help catch bugs
with this case in the future.
