The other checkboxes on this page all have mnemonics. It seems unfair
for the background data usage one to be left out of the party.

NetworkManager supports marking a connection as metered, meaning
that connection is e.g. charged by its usage or extremely limited.
When a network is metered, background network usage must cease
and the behavior of the various OS pieces must be adjusted.
This patch adds a switch to set a connection as metered or not.
The property is imediately propagated to NetworkManager.

This code is fairly independent of the rest, and we don't want
net-device-wifi.c to become too massive and unmaintainable.
The code in connection-editor/ is fairly similar to
nm-connection-editor, with some simplification because we
currently only edit wireless connections.
The code in wireless-security/ is almost a straight copy
of the same code in nm-connection-editor, with some changes
to the .ui files to make them fit better in the new design.
