The long-time goal is to get rid of the /proc/drbd virtual file, and
present the information that was there in a more structured way in /sys.

This patch adds a very first step into that direction. Later we intend to
have here things like the connections state, device roles, statistics
counters there.

When coming up with the layout we used the sysfs presence of software raid 
as example.

I have removed it from this pull-request, so that there is more time for
consideration before the next merge window.
