This changeset is some pre-requisite boilerplate that is required for introducing CSI volume management for client nodes. It extracts out fingerprinting logic from the csi instance manager. This change is to facilitate reusing the csimanager to also manage the node-local CSI functionality, as it is the easiest place for us to guaruntee health checking and to provide additional visibility into the running operations through the fingerprinter mechanism and goroutine. It also introduces the VolumeMounter interface that will be used to manage staging/publishing unstaging/unpublishing of volumes on the host.
