and by doing so, fix a bug where the stats providers report a directory is not found after a pod's storage is removed

ab0f274a6f kubelet/stats: update cadvisor stats provider with new log location
in https://github.com/kubernetes/kubernetes/pull/74441,
the namespace and name were added to the pod log location.

However, cAdvisor stats provider wasn't correspondingly updated.

since CRI-O uses cAdvisor stats provider by default, despite being a CRI implementation,
eviction with ephemeral storage and container logs doesn't work as expected, until now!

da988294ec Work-around for missing metrics on CRI-O exited containers
HPA needs metrics for exited init containers before it will
take action. By setting memory and CPU usage to zero for any
containers that cAdvisor didn't provide statistics for, we
are assured that HPA will be able to correctly calculate
pod resource usage.

Move from glog to klog
- 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

42398825ed Move the kubelet network package down to dockershim
With CRI, kubelet no longer sets up networking for the pods. The
dockershim package is the rightful owner and the only user of the
newtork package. This change moves the package into dockershim to make
the distinction obvious, and untangles the codebase.

The`network/dns`is kept in the original package since it is only used by
kubelet.

fix network value for stats summary for multiple network interfaces

This PR is part of [Heapster #1788](https://github.com/kubernetes/heapster/pull/1788). 

The original reason is when there are more than one none `lo`, `docker0`, `veth` network interfaces instead of just one `eth0`, the network interface value is only partial and does not correct. For now, summary stats api only gets the eth0 network interface values.

The original issues about this can be find in [Heapster #1058](https://github.com/kubernetes/heapster/issues/1058) and [Cadvisor #1593](https://github.com/google/cadvisor/issues/1593).

```release-note
Fix stats summary network value when multiple network interfaces are available.
```

84b0e82db4 Integrating cadvisor stats to CRI Pod stats collection
This commit addresses the issue described here
https://github.com/kubernetes-incubator/cri-containerd/issues/341
The changes include using cadvisor stats in addition to CRI stats
for CRI runtimes. As described in the issue above , the CRI stats
currently doesnt provide all the necessary stats for the kubelet.
This commit addreses the need to extract stats from cadvisor which
is not available as CRI stats.
