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].
