test/vhost: add vfio-user option

Browse Source 
Add option to connect Qemu VMs to vfio-user sockets.
This needs additional option to vhost_run to run nvmf_tgt
instead of vhost binary (currently the only way to create
vfio-user sockets) and an additional function to find
connected devices in the VMs.
