Release note:

This reverts commit 8d2832021ad049eee6f184315a10f3abe18036f9.
- 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

created previously in this series.

Migrate remaining pkg/kubelet/cm/ top level files to structured logging
The cpuset.Parse function missed a couple bad input cases, specifically
"1--3" and "10-6".  These were silently ignored when they should instead
be flagged as invalid.

This now catches these cases and expands the unit tests for cpuset to
cover them (and other negative test cases as well).

This code was pulled out of the CPUManager in the kubelet (which I am one of the maintainers of). In general, the change looks good, just one small comment about the OWNERS file. Otherwise:
