provisioning: Add httpd transport (alias of softAP, netif agnostic)

Browse Source 
The script works the same way with httpd and softap mode, but it's a bit
confusing to provision the device over Ethernet or USB and call the
transport "softap". That's why we introduce an alias called httpd which
uses the same idea (http server with service name), but that service
runs on any interface (where the specified service is available)

* `console` - for debugging via console-based provisioning
* The client->device commands are printed to STDOUT and device->client messages are accepted via STDIN.
* This is to be used when the device is accepting provisioning commands on UART console.
* `httpd` - the script works the same as for `softap`. This could be used on any other network interface than WiFi soft AP, e.g. Ethernet or USB.
* `--service_name <name>` (Optional)
- When transport mode is `ble`, this specifies the BLE device name to which connection is to be established for provisioned. If not provided, BLE scanning is initiated and a list of nearby devices, as seen by the host, is displayed, of which the target device can be chosen.
- When transport mode is `softap`, this specifies the HTTP server hostname / IP which is running the provisioning service, on the SoftAP network of the device which is to be provisioned. This defaults to `192.168.4.1:80` if not specified
- When transport mode is `softap` or `httpd`, this specifies the HTTP server hostname / IP which is running the provisioning service, on the SoftAP network (or any other interface for `httpd` mode) of the device which is to be provisioned. This defaults to `192.168.4.1:80` if not specified
* `--ssid <AP SSID>` (Optional)
- For specifying the SSID of the Wi-Fi AP to which the device is to connect after provisioning.
