For P2P connections it makes sense to bind the connection to the status
of the operation that is being done. One example is that a wifi display
(miracast) P2P connection should be shut down when streaming fails for
some reason.

This new helper class allows binding a connection to the presence of a
DBus path meaning that it will be torn down if the process disappears.
