Manager: detect thunderbolt system support
Created by: gicmo
It would be good if the daemon could detect that there is support for thunderbolt present in a computer. This is not as easy as one would hope, because the thunderbolt controller(s) can be powered down and then /sys/bus/thunderbolt
is empty (or even missing?).

could remember that a thunderbolt host controller was present at earlier times by storing it in the database. Not sure if there are hot-pluggable thunderbolt controller, but that seems like a corner case.
We could also use force power the controller every time the daemon starts up (issue #50 (closed)) or if we have nothing in the database.
