Using this option, one can avoid systemd checks that would establish whether
this hostmonitor is running alongside Corosync and Pacemaker (the ``cluster``
stack) or Pacemaker Remote (the ``remote`` stack).

The default (``autodetect``) ensures backward compatibility and means systemd
is used to check the stack.
