Don't include 'nmcli -f all con' output in bug report (for privacy)

[Nate Eldredge]

The apport bug reporting hooks for this package (/usr/share/apport/package/hooks/source_network-manager{,-applet}.py) include the output of `nmcli -f all con`. This lists all wifi SSIDs that the user has ever connected to, and the date of last connection. I think this is a privacy problem, as it tends to reveal the user's recent whereabouts, and it's posted publicly on launchpad. (Imagine for instance an entry for "LoveMotelGuestWifi" at a time when the user had said they were at the office...)

It is disclosed to the user before the report is sent, but only if they think to expand that item in the "Send / Don't send" dialog (which is not descriptively labeled), and there is no way to opt out of it. You can delete it manually from launchpad afterward, which is what I am going to do with this bug report, but I doubt most people would know to do that.

This info should probably not be included at all, or if it is, it should be sanitized. Also, it might be a good idea to purge launchpad of all such files.

(Marking this as "security" in case you consider this kind of a privacy leak to be something the security team should handle. If not, feel free to demote it to an ordinary bug.)
