Change of openstackrapid directory name
The scripts are orrignally written to support an OpenStack deployment. We are now making changes to support container environments, hence renaming the directory to rapid. Change-Id: Icaa2fad83c6da451eee733934151e98e9cd07de4 Signed-off-by: Luc Provoost <luc.provoost@intel.com>
