These commands show the information about active backend network devices.
Changes from v2
---------------
- Got rid of vlans, a separate command for them will be created if needed
- Removed socket as a type (it is used to connect vlans)
- 'script', 'downscript' and 'vhostfd' are now optional when type is 'tap'
- Reworded the explanation of 'peer'

+Each device is represented by a json-object. The returned value is a json-array
+of all devices.
+
+Each json-object contains the following:
+
+- "id": the device's ID, must be unique (json-string)
+- "type": device type (json-string)
+ - Possible values: "tap", "user", "vde"
+- "peer": ID of the frontend guest device, if not available means that this
+ netdev is not connected to a guest device yet (json-string, optional)
+- "info": json-object containing the configuration information about the
device.
+ - When "type" is "tap", the following values might be available:
+ - "fd": available if connected to an already opened TAP interface
+ (json-int, optional)
+ - "script": path to an script used to configure the interface,
+ available only if an script is used. (json-string, optional, only
+ present if "fd" is not present)
+ - "downscript": path to an script used to deconfigure the
interface,
+ available only if an script is used. (json-string, optional, only
+ present if "fd" is not present)
+ - "ifname": name of the attached host interface (json-string, only
+ present if "fd" is not present)
+ - "vhost": vhost acceleration status, true if enabled, false
+ otherwise (json-boolean)
+ - "vnet_hdr": true if the IFF_VNET_HDR flag must be set and is in
+ use, false otherwise (json-boolean)
+ - "vhostfd": fd used to connect the device to an already opened
+ vhost net device (json-int, optional)
+ - "sndbuf": send buffer size, in bytes (json-int)

+ - "sock": path to the VDE listening socket (json-string)
+ - "port": port number connected to virtual switch (json-int)
+ - "group": group name (json-string)
+ - "mode": permission mode, in octal (json-int)
+ - When "type" is "user", the following values might be available:
+ - "hostname": client hostname reported by the builtin DHCP server,
+ (json-string, optional)
+ - "restrict": true if guest is isolated from the host,
+ false otherwise (json-boolean)
+ - "net": network address (json-string)
+ - "netmask": netmask (json-string)
+ - "host": guest-visible address of the host (json-string)
+ - "tftp": root directory of the built-in TFTP server (json-string,
+ optional)
+ - "bootfile": BOOTP filename (json-string, optional)
+ - "dhcpstart": the first of the 16 IPs the built-in DHCP server can
