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.

866c52c8a9 kubelet: fix duplicated status updates at pod cleanup 
cleanupTerminatedPods is responsible for checking whether a pod has been
terminated and force a status update to trigger the pod deletion. However, this
function is called in the periodic clenup routine, which runs every 2 seconds.
In other words, it forces a status update for each non-running (and not yet
deleted in the apiserver) pod. When batch deleting tens of pods, the rate of
new updates surpasses what the status manager can handle, causing numerous
redundant requests (and the status channel to be full).

This change forces a status update only when detecting the DeletionTimestamp is
set for a terminated pod. Note that for other non-terminated pods, the pod
workers should be responsible for setting the correct status after killling all
the containers.
