Currently, this recipe only supports daily scheduling via a cron job.
This commit adds support for systemd, including systemd service and
systemd timer. When the corresponding distro feature is enabled the
systemd variant will be used. The timer granularity and its accuracy
are also configurable.

Changes in v2:
- Make the systemd timer configurable (as this is distribution or target 
specific)
