No daemon, no PID files, no init script
Created by: SunilMohanAdapa
We pretty much only run in systemd environment and I don't see that changing any time soon. By relying on it, we can reduce some burden. Remove init script.
Daemonizing is not needed for systemd. Remove code related to daemonization.
PID files are not needed for systemd too. Remove them as well. Update documentation.
