I moved to implementation on this, but I hit an issue with the original

My current implementation is a python script run from tox. But I can't 
use the standard tox jobs as they have "hosts:all" tasks all over them 
which are bypassed[1] if the job is run on the executor.

[1] See 

Ideally I would define my own narrow playbook to run the script, without 
inheriting from the standard tox job. However the current script 
requires some dependencies to be installed (openstack-governance, yaml...).

Here are the options I see:

1- reimplementing most of the unittests/tox job logic in 
"hosts:localhost" playbook(s) -- would mean lots of copypaste, does not 
rhyme so well with "lightweight", and increases execution times 

2- rewrite the Python script so that it can run on stdlib -- not sure I 
want to write a YAML parser from scratch though

3- Abandon the idea of running on the executor -- the trick is that for 
such a short job the overhead of requesting a test node is a bit heavy, 
and we want to run the job on every vote change on release requests

Other ideas?
