This commit makes it so that the nodeplugin shares its internal /cvmfs autofs root via a hostPath instead of an emptyDir. kubelet periodically scrapes metrics from all emptyDir volumes by walking trough them recursively, stat()-ing each item. This however resets the autofs mount expiry timeout, making it impossible to automatically unmount unused CVMFS repos. The workaround for this is to share /cvmfs via a hostPath which is not included by the metrics, avoiding the issue.
