Mark puppet-lint jobs as voting

Since the introduction of non-voting puppet-lint jobs for OpenStack
puppet modules, a lot of cleanup have been done in the manifests.

All puppet-lint ERRORS have been fixed and builds are now passing
successfully. We wish to enable voting for puppet-lint jobs.

We are aware that WARNINGS are still present but won't fail the build.
Fixing WARNINGS will be a work in progress in the following months.
