func (r *ResourceCollector) Start() {
// Get the cgroup container names for kubelet and runtime
kubeletContainer, err := getContainerNameForProcess(kubeletProcessName, "")

if err == nil {
systemContainers = map[string]string{

}
r.buffers[name] = append(r.buffers[name], computeContainerResourceUsage(name, oldStats, newStats))

apiserver: pass the parent request context when creating InputStream
**What this PR does / why we need it**:
This ensures that request cancellation will be propagated properly to
the client used to create the stream. Without this fix, the apiserver
and the kubelet may leak resources (e.g., goroutine, inotify watches).
One such example is that if user run `kubectl logs -f <container that
don't produce new logs)` and then enter ctrl-c, both kubelet and
apiserver will hold on to the connection and resources indefinitely.

I would like to add additional step of waiting up to 5 minutes to make sure that all daemonsets are properly booted before we start latency measurements.

Synchronous & unbatched audit log writes
**What this PR does / why we need it**:
When enabling buffered audit log file writes to reduce latency under high load, we shouldn't be batching the writes, as the large data write can have an inverse (though unpredictable) impact. Additionally, batched audit log writes should not be done asynchronously, as this just creates lock contention on the log writer.
