b351819679 bdev/virtio/rpc: allow listing created devices
Listing them through get_bdevs is not enough. Some
devices might not have any LUNs presented while expecting
some to be hotplugged in the future.

```
$ rpc.py get_virtio_scsi_devs
[
  {
    "virtio": {
      "vq_count": 18,
      "type": "user",
      "socket": "/tmp/vhost.0",
      "vq_size": 512
    },
    "name": "VirtioScsi0"
  }
]
```

17d55c9fd4 bdev/virtio: added vhost-blk initiator
Briefly tested with SPDK target via bdevio
through both vhost-user and QEMU's virtio-pci.

vhost-blk driver is not mentioned in any doc yet.
A virtio-blk bdev can be created as following:

`construct_virtio_user_blk_bdev /tmp/virtio.0 MyVirtioBlk0 --vq-count 16`
`construct_virtio_pci_blk_bdev 0000:01:00.0 MyVirtioBlk1`

or

```
[VirtioUser0]
  Path /tmp/vhost.0
  Type Blk
  Queues 16

[VirtioPci]
  Enable Yes
```

If `Type` field is not present, the VirtioUser
section will be parsed as a SCSI one, preserving
backward compatibility.

0d6a37c7d9 bdev/virtio/rpc: add RPC to attach virtio-pci device
`rpc.py construct_virtio_pci_scsi_bdev <bdf> <name>`

The RPC internals reuse the struct definition and callback
functions from virtio-user equivalents

568cf46c5d bdev/virtio/rpc: cleanup construct_virtio_user_bdev code
Make it non vhost-user specific. The same
code will be later reused by upcoming
construct_virtio_pci_bdev RPC call.

argument 'name' was added as optional but it was requiered
