Subject: [PATCH] Register the worker daemon with systemd

When installing a custom initscript for a worker daemon, reload
systemd so it will pick that up before attempting to start the
service. Wrap it in a conditional check for Ubuntu 16.04 or later,
since earlier releases used upstart as their init instead of
systemd. Make sure the initscript template uses a distinct
"provides" key for each instance of the service as well.

This implementation is copied from the puppet-zuul module.
