Automatic merge from submit-queue

Generates DELETE pod update operations

fixes #27105

Generates DELETE pod update operations  to make the code and log more intuitive.

1. main refactoring is in `kubelet/config`
2. kubelet will log if it received DELETE, just like other OPs

Yu-Ju Hong deafa44d61 kubelet: send all recevied pods in one update 
The kubelet sync loop relies on getting one update as the signal that the
specific source is ready. This change ensures that we don't send multiple
updates (ADD, UPDATE) for the first batch of pods. This is required to prevent
the cleanup routine from killing pods prematurely.

Yu-Ju Hong 712612c2dc Treat first-seen, non-pending pods as updates 
Kubelet doesn't perform checkpointing and loses all its internal states after
restarts. It'd then mistaken pods from the api server as new pods and attempt
to go through the admission process. This may result in pods being rejected
even though they are running on the node (e.g., out of disk situation). This
change adds a condition to check whether the pod was seen before and categorize
such pods as updates. The change also removes freeze/unfreeze mechanism used to
work around such cases, since it is no longer needed and it stopped working
correctly ever since we switched to incremental updates.

Tim Hockin e6df0b1a24 Convert validation to use FieldPath 
Before this change we have a mish-mash of ways to pass field names around for
error generation.  Sometimes string fieldnames, sometimes .Prefix(), sometimes
neither, often wrong names or not indexed when it should be.

Instead of that mess, this is part one of a couple of commits that will make it
more strongly typed and hopefully encourage correct behavior.  At least you
will have to think about field names, which is better than nothing.

It turned out to be really hard to do this incrementally.

Dr. Stefan Schimanski 5cfeb53057 Enforce an initial empty SET PodConfig 
In PodConfigNotificationIncremental PodConfig mode, when no pods are available
for a source, the Merge function correctly concluded that neither ADD, UPDATE nor
REMOVE updates are to be sent to the kubelet. But as a consequence the kubelet will
not mark that source as seen.

This is usually not a problem for the apiserver source. But it is a problem for
an empty "file" source, e.g. by passing an empty directory to the kubelet for
static pods. Then the file source will never be seen and the kubelet will stay
in its special not-all-source-seen mode.

Yu-Ju Hong 5abdfcdfe6 kubelet: fix all sources ready condition 
The current implementation considers a source seen when it receives a SET at
kubelet/config/config.go. However, the main kubelet sync loop may not have
received the pod update from the source via the channel. This change ensures
that kubelet would consider all sources are ready only after the sync loop has
seen all the sources.

Yu-Ju Hong b906e34576 kubelet: trigger pod workers independently 
Currently, whenever there is any update, kubelet would force all pod workers to
sync again, causing resource contention and hence performance degradation.

This commit flips kubelet to use incremental updates (as opposed to snapshots).
This allows us to know what pods have changed and send updates to those pod
workers only. The `SyncPods` function has been replaced with individual
handlers, each handling an operation (ADD, REMOVE, UPDATE). Pod workers are
still triggered periodically, and kubelet performs periodic cleanup as well.

This commit also spawns a new goroutine solely responsible for killing pods.
This is necessary because pod killing could hold up the sync loop for
indefinitely long amount of time now user can define the graceful termination
period in the container spec.
