New python script to check openstack deployment
This is a crucial part of functest env prepare. The former check_os.sh is missing some error control and is sometimes trying to connect to an empty endpoint if the sed/awk commands were wrong. This python script is more robust in that sense. You can see an example of execution in [1].
