Title: doc openstack builder: region req'd only for rackspace

Modify openstack builder doc to say that specifying a region is only required for public rackspace and is NOT required for a private openstack cloud.

Region was modified to only be required for rackspace in the code by https://github.com/mitchellh/packer/pull/1418
