Previously, the service file's name is 'k8s_${POD_UID}.service',
which means we need to `systemctl daemon-reload` if the we replace
the content of the service file (e.g. pod is restarted).
However this makes the journal in the previous pod get disconnected.
This PR solves the issue by using the unique rkt uuid as the service
file's name. After the change, the service file's name will be:
'k8s_${rkt_uuid}.service'.

add a delayed queueing option to the workqueue
Adds delayed requeuing to the workqueue so that I requeue an item to be retried at some later time in my controller with a series of backoff rules. It lets me have the best of the retryManager and the work queue de-duping. Tracking failures and backoffs is on the caller
@smarterclayton @pweil- this would help us move to using the informer everywhere and de-duping at that level.

Use OomScoreAdj in kubelet for newer docker api
fixes: #20121
Related: client side PR [pull 454](https://github.com/fsouza/go-dockerclient/pull/454)
Godeps has already been updated to `0099401a7342ad77e71ca9f9a57c5e72fb80f6b2`, which included client side's modification. But it seems too aggressive to upgrade the docker api version of kubelet.

Fixed mounting with containerized kubelet
`NsenterMounter.IsLikelyNotMountPoint()` should return `ErrNotExist` when the
checked directory does not exists - the regular mounted does this and
some volume plugins depend on this behavior.
See for example: https://github.com/kubernetes/kubernetes/blob/master/pkg/volume/aws_ebs/aws_util.go#L72

Add godoc to kubelet/volumes.go
Noticed that `mountExternalVolumes`, of all things, was missing Godoc while working w/ @screeley44. Decided to add some tonight since I have been making noise about grokkability of the kubelet lately.
