pkg/client/leaderelection: log err when retrieving endpoint
The leader election code currently suppresses errors when trying to retrieve an endpoint. This can lead to difficult to debug situations.
In the case of a mis-configured controller-manager or scheduler - where they fail to contact an apiserver - this currently leads to no log output in the default case, or `failed to renew lease foo/bar` in `--v=4`, which isn't very actionable.

fix updatePod() of RS and RC controllers
Fix updatePod of replication controller manager and replica set controller to handle pod label updates that match no RC or RS.
Fix#27405
If the mount operation exceeds the timeout, it will return an error and the
pod worker will retry in the next sync (10s or less). Compared with the
original value (i.e., 10 minutes), this frees the pod worker sooner to process
pod updates, if there are any.
This commit adds a new volume manager in kubelet that synchronizes
volume mount/unmount (and attach/detach, if attach/detach controller
is not enabled).
This eliminates the race conditions between the pod creation loop
and the orphaned volumes loops. It also removes the unmount/detach
from the `syncPod()` path so volume clean up never blocks the
`syncPod` loop.

kubelet/rkt - treat pod container as the infra - only network stats
As no "container name" annotation was being applied to the pod as a whole, the rkt pod container didn't have a container name label. This means that in stat/summary it came up as a nameless container that belonged to the pod.
this was problematic as it caused double counting of container stats.
this adds a container name annotation to the pod level which will be overridden during label creation by annotations of the same name at the container level for the containers themselves.
stats/summary will do the right thing as it will treat it the same as the infra container, just get network stats from it.

Rbac api group make subject apiversion optional
This fixes the verification for the "apiVerion" field in the RBAC subject and makes it optional. This field isn't used and currently won't pass validation if it's filled.
```yml
kind: ClusterRoleBinding
apiVersion: rbac.authorization.k8s.io/v1alpha1
metadata:
name: admins
subject:
- kind: User
name: admin-user
# apiVersion: "entering anything here will fail validation"
roleRef:
kind: ClusterRole
name: admin
apiVersion: rbac.authorization.k8s.io/v1alpha1

Let kubelet log the DeletionTimestamp if it's not nil in update
This helps to debug if it's the kubelet to blame when a pod is not deleted.
Example output:
```
SyncLoop (UPDATE, "api"): "redis-master_default(c6782276-2dd4-11e6-b874-64510650ab1c):DeletionTimestamp=2016-06-08T23:58:12Z"

Fix docker api version in kubelet
There are two variables `dockerv110APIVersion` and `dockerV110APIVersion` with
the same purpose, but different values. Remove the incorrect one and fix usage
in the file.
