_inherit_properties_from_image checks 'arch' instead of 'architecture'

[Lorin Hochstein]

In nova/compute/api.py, the _inherit_properties_from_image method appears to be retrieving the 'arch' property from an image to get the architecture (if any) associated with an image:

        options_from_image = {'os_type': prop('os_type'),
                              'architecture': prop('arch'),
                              'vm_mode': prop('vm_mode')}

However, other parts of the code seem to assume that this property is called 'architecture' on the image, not 'arch'. For example, in that same file, the _instance_supported method has:

            # grab the architecture from glance
            architecture = image['properties'].get('architecture', 'Unknown')

and the nova/scheduler/filters/image_props_filter.py:instance_supported method has:

        img_arch = image_props.get('architecture', None)
