# What this is: An OpenStack Congress policy test. Sets up and validates policy
# creation and execution for:
# 1) Detecting that a reserved subnet has been created, by mistake. "Reserved"
#    in this example means e.g. not intended for use by VMs.
#
# Status: this is a work in progress, under test. 
#
# Prerequisite: 
# - OpenStack deployment with Congress service activated.
# - OpenStack CLI environment variables setup e.g. via admin-openrc.sh script.
# How to use:
#   # Create Congress policy and resources that exercise policy
#   $ bash reserved_subnet.sh
#   # After test, cleanup
#   $ bash reserved_subnet-clean.sh
