zfs pool plugin: implement method to get qemu blockdevice options

Browse Source 
ZFS does not have a filesystem_path() method, so the default
implementation for qemu_blockdev_options() cannot be re-used. This is
most likely, because snapshots are currently not directly accessible
via a filesystem path in the Proxmox VE storage layer.
