Add a new call to VolumePlugin interface and change all its
implementations.
Kubelet's VolumeManager will be interested whether a volume supports
mounting with -o conext=XYZ or not to hanle SetUp() / MountDevice()
accordingly.
The field in fact says that the container runtime should relabel a volume
when running a container with it, it does not say that the volume supports
SELinux. For example, NFS can support SELinux, but we don't want NFS
volumes relabeled, because they can be shared among several Pods.
- 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

Since the runtime may try to create mount points within
the sandbox, it will fail if the mount point is within
a read-only API data volume, like a secret or configMap
volume.
Create any needed mount points during volume setup.
This implements Bulk volume polling using ideas presented by
justin in https://github.com/kubernetes/kubernetes/pull/39564
But it changes the implementation to use an interface
and doesn't affect other implementations.
