CRI: Add missing sandbox in runningPod.
Add a container that represents pod sandbox when converting the
pod status to runningPod.
Without the change, `kubeGenericRuntimeManager.killPodWithSyncResult()` will not kill any sandboxes.

etcd watcher: centralize error handling
We should centralize error handling in watcher in run(). Otherwise this could silently return.
Also we don't need the grpc code checking anymore. It's fixed.

Check init containers in PodContainerRunning
Sometimes when an init container runs and terminates quickly, PodContainerRunning can go into a
state where the pod indicates it's still running, but the container is already terminated. Handle
that condition by returning ErrContainerTerminated when it happens.

[Controller Manager] Fix endpoint controller hot loop and use utilruntime.HandleError to replace glog.Errorf
<!-- Thanks for sending a pull request! Here are some tips for you:
1. If this is your first time, read our contributor guidelines https://github.com/kubernetes/kubernetes/blob/master/CONTRIBUTING.md and developer guide https://github.com/kubernetes/kubernetes/blob/master/docs/devel/development.md
2. If you want *faster* PR reviews, read how: https://github.com/kubernetes/kubernetes/blob/master/docs/devel/faster_reviews.md
3. Follow the instructions for writing a release note: https://github.com/kubernetes/kubernetes/blob/master/docs/devel/pull-requests.md#release-notes
-->
**Why**:
Fix endpoint controller hot loop and use `utilruntime.HandleError` to replace `glog.Errorf`
**What**
1. Fix endpoint controller hot loop in `pkg/controller/endpoint`
2. Fix endpoint controller hot loop in `contrib/mesos/pkg/service`
3. Sweep cases of `glog.Errorf` and use `utilruntime.HandleError` instead.
**Which issue this PR fixes**
Fixes#32843
Related issue is #30629
**Special notes for your reviewer**:
@deads2k @derekwaynecarr
The changes on `pkg/controller/endpoints_controller.go` and `contrib/mesos/pkg/service/endpoints_controller.go` are almost the same except `contrib/mesos/pkg/service/endpoints_controller.go` does not pass `podInformer` as the parameter of `NewEndpointController()`.
So, I didn't wait `podStoreSynced` before `syncService()`(Just leave it as it was). Will it lead to a problem?

[kubelet] Fix oom-score-adj policy in kubelet
Fixes#32238
We have been having this regression since v1.3. It is critical for GKE/GCE deployments of k8s because docker daemon has a high likelihood of being OOM killed which will end up nuking all containers.
The reason for moving from mnt to pid is that docker daemon moves itself into a new mnt namespace with systemd based deployments.

Allow kubectl describe ns to pass if server does not support resource quotas and limit ranges
Fixes https://github.com/kubernetes/kubernetes/issues/32629
Context: federation-apiserver does not support limit ranges and resource quotas. Hence `kubectl describe ns` fails right now.
Fixing it so that `kubectl describe ns` does not error out and atleast prints information about the namespace.
