191666d6a3 Fix computing of cpu nano core usage 
CRI runtimes do not supply cpu nano core usage as it is not part of CRI
stats. However, there are upstream components that still rely on such
stats to function. The previous fix was faulty because the multiple
callers could compete and update the stats, causing
inconsistent/incoherent metrics. This change, instead, creates a
separate call for updating the usage, and rely on eviction manager,
which runs periodically, to trigger the updates. The caveat is that if
eviction manager is completley turned off, no one would compute the
usage.

390b158db9 kubelet: plumb context for log requests 
This allows kubelets to stop the necessary work when the context has
been canceled (e.g., connection closed), and not leaking a goroutine

f5f9893824 Restore cAdvisor prometheus metrics to the main port 
But under a new path - `/metrics/cadvisor`. This ensures a secure port
still exists for metrics while getting the benefit of separating out
container metrics from the kubelet's metrics.

2612e0c78a Move client/unversioned/remotecommand to client-go 
Module remotecommand originally part of kubernetes/pkg/client/unversioned was moved
to client-go/tools, and will be used as authoritative in kubectl, e2e and other places.

Module remotecommand relies on util/exec module which will be copied to client-go/pkg/util

715d5d9c91 Add redirect support to SpdyRoundTripper 
Add support for following redirects to the SpdyRoundTripper. This is
necessary for clients using it directly (e.g. the apiserver talking
directly to the kubelet) because the CRI streaming server issues a
redirect for streaming requests.

Also extract common logic for following redirects.

kubelet: remove the pleg health check from healthz

This prevents kubelet from being killed when docker hangs.

Also, kubelet will report node not ready if PLEG hangs (`docker ps` + `docker inspect`).
