Open Stack

Hi,

I have been working on adding a new CI job that will:
- test if "puppet module build ." command works
- be executed only when touching metadata.json

This job will be useful to validate tarballs can be created when
releasing Puppet modules.

If your project is failing on gate-{name}-puppet-module-build, please
let me know and I'll help in fixing it.
I checked all Puppet OpenStack modules and it worked fine, but I might
have missed something for Infra & Fuel modules / projects that have
metadata.json file.

Thanks,
