Create a standard systemd service file

[daisyUniverse]

Keebie is most usefully run as a daemon, so this seems like a no brainer, having it install as part of a package managers installation script would also be handy

I don't know to first thing about systemd (except that a lot of people hate it), but issue #10 may have relevant info.

The file itself is pretty easy to put together, but the reason I am waiting on this is partially because I don't know what the process is for installing a service file via a package manager - I should probably expand the scope of this issue to be more like 'make a service file in a way that package managers will play nice with' - something I dont know how to do yet, but will soon!

i used the provided service file, i would like to have the layer also printed to syslog but anyway switiching to --verbose does not print to syslog. by calling on terminal it prints all things to stdout

any idea how to add --verbose in keebie.service that it print verbose to log?
