cli: split 'general' into 'nmcli switch' and 'nmcli general' commands

They basically contain operations previously available via 'nmcli nm'.
'nmcli nm' is still kept for backward compatibility.

Usage:
nmcli switch  [all|networking|wifi|wwan|wimax [on/off]]
nmcli general [status|permissions]

Examples:
nmcli switch all         - show all switches
nmcli switch wifi off    - switch Wi-Fi off

nmcli g s    - show NM status
nmcli g p    - show NM permissions
