The parser should not rely on the OS_* environment variables for authentication, as it will fail with more complex setups, when using the "clouds.yaml" configuration file or when being called through osc with arguments instead of environment variables. Moreover, the client should not use "requests" directly to do GETs to access the nova flavors and glance images, but it should use the existing clients. When used through the python-openstackclient it is possible to force the client to request authentication. The authentication will be handled by the client, so that the parser does not need to worry about it (so that authentication plugins can be used). Then, the existing authentication session can be reused for all the client interaction with OpenStack to fetch the flavor and images information. Change-Id: I9f65e7d46686c37bb44ef18756ebd295ee4961de
