always implement the option for multiple volumes and use velero labels for backup exclude

even when include_volumes is set to 'one', this MR now implements that we always have an option to create/mount multiple volumes with a chart (unless you set include_volumes to no). Furthermore, we use the velero labels for excluding volumes from the backup (closes #1 (closed))
