This patch removes GetNUMANodeInfo, cadvisor.MachineInfo will be used
instead of it. GetNUMANodeInfo was introduced due to difference of meaning of
MachineInfo.Topology. On the arm it was NUMA nodes, but on the x86 it
represents sockets (since reading from /proc/cpuinfo). Now it unified
and MachineInfo.Topology represents NUMA node.

containerMap is used in CPU Manager to store all containers information in the node.
containerMap provides a mapping from (pod, container) -> containerID for all containers a pod
It is reusable in another component in pkg/kubelet/cm which needs to track changes of all containers in the node.

These information associatedd with these containers is used to migrate
the CPUManager state from it's old format to its new (i.e. keyed off of
podUID and containerName instead of containerID).
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.
Unfortunately, the NUMA information is not readily available from
cadvisor, so we have to roll the logic to discover it by hand. In the
future, we should remove this custiom code to use the information
provided by cadvisor once it is made available.
- 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

The LocalStorageCapacityIsolation feature added a new resource type
ResourceEphemeralStorage "ephemeral-storage" so that this resource can
be allocated, limited, and consumed as the same way as CPU/memory. All
the features related to resource management (resource request/limit, quota, limitrange) are avaiable for local ephemeral storage.
This local ephemeral storage represents the storage for root file system, which will be consumed by containers' writtable layer and logs. Some volumes such as emptyDir might also consume this storage.
