Bug Description

In multi-region setup Sahara validation of Cinder limits fails since utils/openstack/cinder.py has missing configuration option os_region_name. Example: we have two regions RegionOne and RegionTwo and trying to deploy Hadoop cluster in RegionOne, but Cinder resources validation performs in RegionTwo. Such behaviour is wrong, but acceptable if both regions are acting normal and available. But, if RegionTwo is down, resources validation break along with Hadoop cluster creation.

This can be simple resolved by adding cfg.StrOpt os_region_name to utils/openstack/cinder.py (please see attached patch), but i'm not sure how this will work in single region environment.

Andrew,
Thank you for bug reporting.
It affects other clients like neutron, swift and etc..

os_region_name option already exists but not used in some clients after refactoring.
