Finds and replaces a term in OpenStack endpoints

rewrite_openstack_endpoints.py

# This script finds and replaces a term in the urls of endpoints.
# This is useful because you cannot install Devstack with a
# hostname or domain name, so devstack gets installed with an ip
# and then the script replaces that with a hostname.
