This script will generate the minimal-environment-variables doc
based on the what each services has in the check_required_var field.
Anytime that field is changed run this script and commit the changes.
Since Neutron is a thick container, the script will get a few duplicates
in the neutron-agents field. When Neutron is thinned out, this script
will function normally.
