Merge ~harlowja/cloud-init:yaml-check-python into cloud-init:master

Three problem here is that on a system without Python 2 this will just fail.

As there, nothing is named Python. Virtual env does somewhat of a disservice by providing python 3 as python.

I agree that generally this is a pain. We should have some way to tell cloud init which python to use.

reading this again, i see why you changed validate-yaml.py

I think we can go ahead and take this. with maybe a small change too.

that is a larger change that could maybe also fix it, but i'm somewhat afraid of exporting PYTHON and just seeing things use that.
