Adding startup scripts for salt-bootstrap to use on OpenBSD

These are the scripts to start the services under OpenBSD. I'm currently working on adding OpenBSD support to the salt-bootstrap stuff. This is to match the way it is handled when doing an install via Git on Ubuntu (trying for consistency). The current OpenBSD stuff is at [my fork](https://github.com/kmwhite/salt-bootstrap/tree/feature-add_openbsd_installation_support)
