openstack --help fails if clouds.yaml cannot be read

[Clark Boylan]

Attempting to use the openstack client and the first thing I tried was the help flag, but that fails with:

$ venv/bin/openstack --help
[Errno 13] Permission denied: '/etc/openstack/clouds.yaml'

For most operations this makes sense as access to cloud credentials is required but they should not be required to print basic help info. Openstack client should just print the info instead.
