For non-documented reason we switched from having default value for region empty string to value RegionOne (in tag v0.4.0). RegionOne is default region name in Openstack, but this doesn't justify leaving region to default to this value.
Having region as empty string makes the gophercloud library to pick first found region in the catalog. This can cause potential backwards compatibility issues, which are however very unlikely.
Negative impact of having region default to RegionOne is that it makes the plugin to not work in case user relies on region specified in clouds.yaml. This also looks slightly tricky as region in clouds.yaml doesn't neccesarilly mean that that region should be configured in Cinder.
This change and additional test displays the behavior.
