cli: add verbose output to wifi list mode
When using WiFi in an environment with multiple APs of the same SSID (eg. conference venue, hotels), it is often useful to be able to identify particular APs by their BSSID.
This information is provided in nmcli d wifi list
and can only be made visible
by passing format fields or just using -f all. Neither method is easily
discoverable, and the 'all' format is largely overwhelming.
The patch adds a nmcli d wifi list --verbose
flag, which follows the typical
usage patterns.
