Telemetry stub.

This is experimental, off-by-default, code for developing a telemetry /
tracking configuration module. It is preliminary work for issue #628,
but also for KDE Neon configuration. Any telemetry should conform to
the KDE Telemetry Policy [1] or similar Free Software telemetry policy
(e.g. the Mozilla one).

[1] https://community.kde.org/Policies/Telemetry_Policy

Initial idea is to distinguish three kinds of tracking:
 - installs. This tracks that OS <foo> has been installed somewhere.
   It might send some machine information to a remote server.
 - machines. This enables some kind of machine tracking in the

   installed system, for instance it could enable popcon on
   Debian, or periodic phone-home-pings.
 - users. This enables some kind of telemetry / tracking on the
   installed user in the system.

A simple and transparent setting is to enable install-tracking and set
it to opt-in, and disable machine and user tracking. Explain to the
user that <foo> would like to know when <foo> is installed, and that
the following information <d1>, <d2> will be sent to <url> in accordance
to the <foo> telemetry policy at <url2>.

Work in this branch is subject to VDG review for the visuals, and
privacy oversight by whatever group is responsible for <foo> privacy.

Note that this module makes it *possible* for telemetry configuration
to be visible inside the installer; what distro's do with telemetry
already is entirely outside the scope of this configuration module.
