Add hotspot Wifi informations

[nicolargo]

Description

Thanks to the Wifi lib (https://wifi.readthedocs.io/en/latest/scanning.html), grab and display Wifi hotspot information.

from wifi import Cell, Scheme
Cell.all('wlan0')

This returns a list of Cell objects. Under the hood, this calls iwlist scan and parses the unfriendly output.

Each cell object should have the following attributes:

ssid
signal
quality
frequency
bitrates
encrypted
channel
address
mode

For cells that have encrypted as True, there will also be the following attributes:

encryption_type

Implementation available in the DEVELOP branch.

ONLY for GNU/Linux Operating System

Please test it.

@nclsHart / @notFloran : Can you implement it on the WebUI ?

[notFloran]

@nicolargo I don't have a computer with linux and wifi, can you send me a json of the api results ?

[nicolargo]

@notFloran : Here it is:

curl http://0.0.0.0:61208/api/2/wifi

[{"ssid": "Freebox-40A258", "encrypted": true, "signal": -45, "key": "ssid", "encryption_type": "wpa2", "quality": "65/70"}]

curl http://0.0.0.0:61208/api/2/wifi/views

{"Freebox-40A258": {"ssid": {"decoration": "DEFAULT", "optional": false, "additional": false, "splittable": false}, "encrypted": {"decoration": "DEFAULT", "optional": false, "additional": false, "splittable": false}, "signal": {"decoration": "OK", "optional": false, "additional": false, "splittable": false}, "key": {"decoration": "DEFAULT", "optional": false, "additional": false, "splittable": false}, "encryption_type": {"decoration": "DEFAULT", "optional": false, "additional": false, "splittable": false}, "quality": {"decoration": "OK", "optional": false, "additional": false, "splittable": false}}}

In my example there is only one hotspot. You can have multiple hotspot (one dict per hotspot).
If encrypted = true then encryption_type is eqaul to the encryption algorithm. If encrypted = false then encryption_type is equal to 'null' (do not display in the WebUI).

@notFloran Any news concerning the implementation inside the WebUI ?
