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.

Previously, the state was keyed off of containerID intead of podUID and
containerName. Unfortunately, this is no longer possible as we move to a
to model where we we allocate CPUs to containers at pod adit time rather
than container start time.
This patch is the first step towards full migration to the new
semantics. Only the unit tests in cpumanager/state are passing. In
subsequent commits we will update the CPUManager itself to use these new
semantics.
This patch also includes code to do migration from the old checkpoint format
to the new one, assuming the existence of a ContainerMap with the proper
mapping of (containerID)->(podUID, containerName). A subsequent commit
will update code in higher layers to make sure that this ContainerMap is
made available to this state logic.
- 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
