Public bug reported:

Description
===========
VM resizing should work without ssh connections between compute nodes if they have the same shared storage.

One option is to pass an additional argument if it's a resize on a
shared storage. The same functionality is already implemented for vm
migrations.


Expected result
===============
Resizing on shared storage works without ssh connections between compute nodes.


Actual result
=============
Resizing fails, because it requires an ssh connection between the source and target host.


Environment
===========
1. Openstack version:
nova-api 2:16.0.3-0ubuntu1~cloud0
nova-common 2:16.0.3-0ubuntu1~cloud0
