HPA: Consider unready pods and missing metrics Currently, the HPA considers unready pods the same as ready pods when looking at their CPU and custom metric usage. However, pods frequently use extra CPU during initialization, so we want to consider them separately. This commit causes the HPA to consider unready pods as having 0 CPU usage when scaling up, and ignores them when scaling down. If, when scaling up, factoring the unready pods as having 0 CPU would cause a downscale instead, we simply choose not to scale. Otherwise, we simply scale up at the reduced amount caculated by factoring the pods in at zero CPU usage. The effect is that unready pods cause the autoscaler to be a bit more conservative -- large increases in CPU usage can still cause scales, even with unready pods in the mix, but will not cause the scale factors to be as large, in anticipation of the new pods later becoming ready and handling load. Similarly, if there are pods for which no metrics have been retrieved, these pods are treated as having 100% of the requested metric when scaling down, and 0% when scaling up. As above, this cannot change the direction of the scale. This commit also changes the HPA to ignore superfluous metrics -- as long as metrics for all ready pods are present, the HPA we make scaling decisions. Currently, this only works for CPU. For custom metrics, we cannot identify which metrics go to which pods if we get superfluous metrics, so we abort the scale.

HPA Controller: Use Custom Metrics API This commit switches over the HPA controller to use the custom metrics API. It also converts the HPA controller to use the generated client in k8s.io/metrics for the resource metrics API. In order to enable support, you must enable `--horizontal-pod-autoscaler-use-rest-clients` on the controller-manager, which will switch the HPA controller's MetricsClient implementation over to use the standard rest clients for both custom metrics and resource metrics. This requires that at the least resource metrics API is registered with kube-aggregator, and that the controller manager is pointed at kube-aggregator. For this to work, Heapster must be serving the new-style API server (`--api-server=true`).

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 Change-Id: I92db545ff36fcec83afe98f550c9e630098b3135

Add test coverage for metrics/utilization.go Currently, there is no test coverage for this code. Since it does fairly important calculations, test coverage seems helpful.
