nova: generate per-service initscripts

Rather than use the catch-all "nova-all" initscript, we switch to
one initscript per-service. The old nova-all is still installed, but
not linked as an initscript, so it can be used as a fallback.

In addition to per-service initscripts, we switch to generating those
initscripts from a common template script.
