nova.conf does not have os_region_name parameter

[Fedor Tarasenko]

For the multiple region support, in nova.conf we need to add parameter "os_region_name" to specify the region_name for controller's region, otherwise, nova can not find the right cinder service to call. w/o this configuration, volume attach fails.

Here is the community bug and fix for this in nova code:

[Roman Podoliaka (rpodolyaka)]

Fedor refers to option "os_region_name" in group "cinder" (http://docs.openstack.org/liberty/config-reference/content/list-of-compute-config-options.html)

MOS Puppet team, could you please take a look at this?

At the same time, I'm not convinced this deserves High importance as the option can easily be set after deployment.

Guys, you will need to change nova.conf on all compute nodes, so I cannot say that it is easily can be done from user perspective. raising it to high

Verified on 9.2 snapshot #464.

Steps to verify:
https://paste.mirantis.net/show/2776/

Actual results:
Volume is attached to instance successfully when Cinder endpoint exists in two different regions (RegionOne and RegionTwo). Nova API log doesn't contain any errors.
