Rework the pacemaker_common_functions for M..N upgrades

For N we cannot assume services are managed by pacemaker.
This adds functions to check if a service is systemd or
pcmk managed and start/stops it accordingly. For pcmk,
only stop/disable on bootstrap node for example, whereas
systemd should stop/start on all controllers.

There is also an equivalent change to the check_resource
which has been reworked to allow both pcmk and systemd.
