From: Yasufumi Ogawa <yasufum.o@gmail.com>

For testing behaviours of spp_primary, enable to add arbitrary vdevs
and add `--dry-run` option. These features are mainly for developers.

Dry run is for showing commands without running them actually.

    $ bin/start.sh --dry-run

Any of vdevs and its options can be listed in `PRI_VDEVS` as following
in config file.
    PRI_VDEVS=(
    eth_vhost11,iface=/tmp/sock11,queues=1
    eth_vhost12,iface=/tmp/sock12,queues=1
    )
