Add script to generate the OpenStack defaults

JIRA: FUNCTEST-131

It checks the existing Openstack objects in the current
deployment (i.e. when the script is executed) and it will
create a yaml file to be used afterwards by clean_openstack.

This way, a user can generate the defaults when needed if there
are things that are not meant to be deleted without fear of
using clean_openstack.
