1. move GetOneTimeResourceUsageOnNode() from test/e2e/framework/kubelet/stats.go to getOneTimeResourceUsageOnNode() in test/e2e/framework/resource_usage_gatherer.go
2. copy GetKubeletPods() from test/e2e/framework/kubelet/kubelet_pods.go to getKubeletPods() in test/e2e/framework/util.go

In e2e test framework, ProxyRequest() is called in kubelet e2e test
framework only. In addition, the function works for kubelet as tests
which call the function do. So this moves the function into kubelet
e2e test framework to make the dependency simple.
