Re-mount volumes on a restart or update #27
Description
Currently we use the rclone daemon which needs to be running to keep the fuse mounts for storage working. When the daemon dies all mounts on the node that were mounted by the daemon are dead.
This is a huge problem where any interruption to the node servers results in many users of the driver to be suddenly left without access to the volumes they mounted.
We need to add some code that at startup will check all volumes that use csi-rclone and remount them if necessary. This way restarts or upgrades should result only in a short-lived interruption of access to mounted data.
