SYSTEMD: Don't mix up responders' socket and monitor activation Let's ensure that in case a responder is explicitly configured in the sssd.conf its socket won't even start. The patchset introduces a new binary that will be distributed and will be called before starting the responders' sockets, ensuring the sockets will only start in case the responder is supposed to be socket-activated and its been configured accordingly. Otherwise the responders' socket startup will fail with a quite helpful debug message leading the admins to choose between using systemd or not and what has to be done to achieve their desire. This suggestion came from Sumit Bose. The reason for adding a new binary instead of a simple python script is to avoid dragging unnecessary dependencies to sssd-common package.
