upstart: backport initctl2dot for visualizing init depgraphs

Project Member Reported by kirtika@google.com, Jan 24 2018 
Write a script that when pointed to /etc/init/ folder in a rootfs
takes lines like:
"stop on starting pre-shutdown"
"start on started boot-services"
and generates a directed acyclic graph (by using graphviz/dot?) of the init dependencies, let you see what runs in parallel etc.

Summary: upstart: backport initctl2dot for visualizing init depgraphs (was: upstart: Add a script to chrome os repo that parses /etc/init/*conf to generate a graph of services)
newer versions of upstart already support this: search for "initctl2dot".  i'm not sure how easy it is to backport though.

It's just a python script, so hopefully trivial? Except...it's python3. We don't support that language :)

i think the sticking point is that it's built on the output of `initctl show-config -e` which our upstart version doesn't support afaict
