Unclean shut-down of dlm_controld may trigger a node fencing,
this should not be triggered by mistake.
SIGINT is the natural way to stop dlm_controld started on a terminal
with '-D' for debugging – let this work like SIGTERM.
SIGHUP is often used for config reload. dlm_controld doesn't support
that, but when someone tries this by mistake, this is not a reason to
crash.
