b1a6ee26ef Ignore "no such container" error when generating pod status 
This allows the pod continue to sync if one container in a corrupt state.

bc62096ad5 Clean up host networking plugin checks for docker manager 
We can save a docker inspect in podInfraContainerChanged() because
it's only used within the useHostNetwork() block.  We can also
consolidate some code in createPodInfraContainer() because if
the pod uses the host network, no network plugin will be involved.

Finally, in syncPodWithSyncResult() we can consolidate some
conditionals because both hairpin setup and getting the container
IP are only relevant when host networking is *not* being used.

More specifically, putting the dm.determineContainerIP() call
into the !useHostNetwork() block is OK since if no network plugin
was called to set the container up, it makes no sense to call
the network plugin to retrieve the IP address that it did not
handle.  The CNI plugin even calls back into the docker manager
to GetContainerIP() which grabs the IP from docker, which will
always be "" for host networked containers anyway.

Add a helper method to set the container map and list at the same time, without
having to specify them separately. This reduces the effort required for
adding/modifying tests as well as making the code more concise.

2eb17df46b kubelet: independent pod syncs and backoff on error 
Currently kubelet syncs all pods every 10s. This is not preferred because
 * Some pods may have been sync'd recently.
 * This may cause all the pods to be sync'd at once, causing undesirable
   CPU spikes.

This PR replaces the global syncs with independent, periodic pod syncs. At the
end of syncing, each pod worker will enqueue itslef with a future timestamp (
current time + sync interval), when it will be due for another sync.
 * If the pod worker encoutners an sync error, it may requeue with a different
   timestamp to retry sooner.
 * If a sync is triggered by the update channel (events or spec changes), the
   pod worker would enqueue a new sync time.

This change is necessary for moving to long or no periodic sync period once pod
lifecycle event generator is completed. We will still rely on the mechanism to
requeue the pod on sync error.

This change also makes sure that if a sync does not succeed (either due to
real error or the per-container backoff mechanism), an error would be propagated
back to the pod worker, which is responsible for requeuing.
