Subject: [PATCH 4/5] Monitor: add system timer to run --oneshot periodically

"mdadm --monitor --oneshot" can be used to get a warning
if there are any degraded arrays.  It can be helpful to get
this warning periodically while the condition persists.

This patch add a systemd service and timer which can
be enabled with
   systemctl enable mdmonitor-oneshot.service

and will then provide daily warnings.
