systemd auto install

Basic info
Game: LinuxGSM general
Distro: Systemd supported distros

Is your feature request related to a problem? Please describe.
Systemd is the standard way of managing services and starting on boot. However, it is not "simple" to use for a standard admin. It would be a good idea for convenience for the LinuxGSM script to install systemd script specific to itself and be able to also remove the systemd script as well.

Describe the solution you'd like
Automated installation of systemd using a new LinuxGSM command

Describe alternatives you've considered
The admin manually adding the script

I perhaps have some work to better support systemd including multiple server instances per game.

See https://github.com/Stormwind99/LinuxGSM/tree/better-for-systemd

Here is my use case (and thus current test case) for Minecraft, where I have multiple Minecraft servers running. The fork branch above creates a pid file for each server used below in the systemd minecraft.service file, and also makes a separate tmux server instance for each game server instance (so systemd isn't confused by a different slice's process (from another game instance) starting the current slice's process.
