Fix kubelet PVC stale metrics
**What this PR does / why we need it**:
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 internal
stats.
Currently, if a PV (bound to a PVC `testpv`) is attached and used by node A, then migrated to node B or just deleted from node A later. `testpvc` metrics will not disappear from kubelet on node A. After a long running time, `kubelet` process will keep a lot of stale volume metrics in memory.
For these dynamic metrics, it's better to use a collector to collect metrics from a data source (`StatsProvider` here), like [kube-state-metrics](https://github.com/kubernetes/kube-state-metrics) scraping metrics from kube-apiserver.
