This patch removes pkg/util/mount completely, and replaces it with the
mount package now located at k8s.io/utils/mount. The code found at
k8s.io/utils/mount was moved there from pkg/util/mount, so the code is
identical, just no longer in-tree to k/k.
- 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

Google's configure-helper.sh script bind-mounts /var/lib/kubelet somewhere
into /home/kubernetes and thus every mount that Kubernetes does is visible
twice in /proc/mounts.
iSCSI and RBD should not rely on counting on entries in /proc/mounts and
unmount device when Kubernetes thinks it's unusued. Kubernetes tracks
the mounts by itself and most of other volume plugins rely on it safely.
With central attachdetach controller, we don't need to lock the image
any more. But for backward compatibility, we should:
1) Check if the image is still used by nodes running old kubelet in
attaching.
2) Clean old rbd.json file and remove lock if found in detaching.
1) Modify rbdPlugin to implement volume.AttachableVolumePlugin
interface.
2) Add rbdAttacher/rbdDetacher structs to implement
volume.Attacher/Detacher interfaces.
3) Add mount.SafeFormatAndMount/mount.Exec fields to rbdPlugin, and
setup them in rbdPlugin.Init for later uses.
Attacher/Mounter/Unmounter/Detacher reference rbdPlugin to use mounter
and exec. This simplifies code.
4) Add testcase struct to abstract RBD Plugin test case, etc.
5) Add newRBD constructor to unify rbd struct initialization.
