democratic-csi: Initial deployment

Deploying _democratic-csi_ to manage PersistentVolumeClaim resources,
mapping them to iSCSI volumes on the Synology.

Eventually, all Longhorn-managed PVCs will be replaced with Synology
iSCSI volumes.  Getting rid of Longhorn should free up a lot of
resources and remove a point of failure from the cluster.
