fd3432ef05 add dynamic config metrics 
This PR exports config-releated metrics from the Kubelet.
The Guages for active, assigned, and last-known-good config can be used
to identify config versions and produce aggregate counts across several
nodes. The error-reporting Gauge can be used to determine whether a node
is experiencing a config-related error, and to prodouce an aggregate
count of nodes in an error state.

fecff55c59 Fix kubelet PVC metrics using a volume stats collector. 
Volumes on each node changes, we should not only add PVC metrics into
gauge vector. It's better use a collector to collector metrics from
stats.

148588e6a1 1) Add docker operation timeout metrics. 
2) Cleanup kubelet stats and add runtime operation error and timeout
rate monitoring.
3) Monitor runtime operation error and timeout rate in
kubelet perf.

3de94cd23c Supply volume fs metrics to server/stats/handler.go 
* Metrics will not be expose until they are hooked up to a handler
* Metrics are not cached and expose a dos vector, this must be fixed before release or the stats should not be exposed through an api endpoint

7d180b337b Record pleg pod relist interval and latency 
Relisting latency/interval affects how quick kubelet discovers changes. Record
the metrics in Prometheus to surface such information.

f96a8d0935 Kubelet: record the initial pod processing latency 
Add a new latency metric for the time from seeing the pod for the first time
to starting a pod worker for it.

Also, change PodStartLatency to include this initial processing latency.

9eb01a6da1 Make SyncPodSync as the default SyncPodType. 
We would like the default to be sync instead of create to easily differentiate
create operations in empty metrics map.

6b3a6e6b98 Make copyright ownership statement generic 
Instead of saying "Google Inc." (which is not always correct) say "The
Kubernetes Authors", which is generic.

090d0c95fa Remove ImagePull metric in Kubelet. 
There is an equivalent metric from our Docker metrics and this one is
harder to maintain with the RuntimeHooks.

73c2338320 Refactor build/parse dockername. #3511 
Functions Build/ParseDockerName now work with struct instead of the long
list of arguments. This new struct also was reused in the kubelet.go
instead of auxilary podContainer struct.
