adding jobAttrs which is filled from jobs contents

Purpose: Allow overwriding of properties such as:
           config.jobAttrs.sshd.startOn = "never";

thanks to Nicolas Pierron for reviewing and
extending nixpkgs to make this possible

I'll convert most of the jobs ASAP so please don't care
about the depreceateion much right now
