Open Stack

Hi,

From my previous 3K+ nodes 6+ regions OpenStack operations experience in Yandex, I found useless to have Cinder and Neutron services in cross-region manner.

BTW, nova-neutron cross-region interactions are still legitimate use case: you may utilize one neutron for many nova regions.
