3072754c8b Avoid unnecessary GET request when updating pod status 
When sending out an pod status update, kubelet

GETs the pod from the apiserver
Terminates if the apiserver returns an not found error; otherwise, proceed to
to update.
Even after a pod has been deleted, there might still be queued up updates for
the pod. This leads to expensive, unncessary GET operations. The situation is
worse when there are batch creation/deletion of a significant number of pods
(e.g., E2E tests), leaving many updates in the queue.

This change checks whether a pod exists before GET the pod from the apiserver
to avoid redundant GETs.

575812787d Replace --resource-container and --system-container with 
`--kubelet-cgroups` and `--system-cgroups` respectively.
Updated `--runtime-container` to `--runtime-cgroups`.
Cleaned up most of the kubelet code that consumes these flags to match
the flag name changes.

392fc6668f Jittering periods of some kubelet's sync loops: 
- pod_workers: pod syncing
- prober workers: container syncing

In order to synchronize the current state of Kubernetes's objects (e.g. pods, containers, etc.),
periodic synch loops are run. When there is a lot of objects to synchronize with,
loops increase communication traffic. At some point when all the traffic interfere cpu usage curve
hits the roof causing 100% cpu utilization.

To distribute the traffic in time, some sync loops can jitter their period in each loop
and help to flatten the curve.
