Use systemd notify protocol when services have started
Description
A smarter way to tell systemd when services have successfully started than just waiting 1 second and hoping.
How Has This Been Tested?
Deployed on xcaltst, and checked the logs in the journal. The line from systemd saying that the service is started comes after the service's own startup stuff:
