Wish: Provide systemd service file for people to use.

[markstos]

Right now when sshtron is run by systemd, the colors don't work. See:

http://unix.stackexchange.com/questions/352937/ansi-colors-when-using-systemd-service

From what I can tell, sshtron uses a color library, which in turn uses library to check is there's a terminal connected to decide whether to use colors or not, which boils down to this line:

https://github.com/mattn/go-isatty/blob/master/isatty_linux.go#L14

The logic using TTY detection to decide if a server should output color seems flawed if that's what' going on. The server might be not connected to a TTY even if the clients are.

systemd does have some options to connect a service to a TTY documented in man systemd.exec, but usually services aren't connected to TTYs, their clients are.

In any event, providing a working systemd .service file would be of interest to people who want to manage sshtron as a standard system service.

I got it working in color under a Docker container by attaching it to tty with docker run -t.

Thanks for the PR @ali-yousuf-10p! Just merged it.

@markstos: totally with you & think that providing a systemd service would be awesome. Any chance you'd be interested in submitting a PR for that?

Work's crazy for me right now and I don't think I'll have a chance to get to this for at least a few months.
