XenAPINFS: Volume always uploaded as vhd/ovf

[Mate Lakat]

# Create a qcow Image from a Volume

## Step 1. Generic Setup
You have a cinder box running XenAPINFS

    cd devstack
    . openrc admin
    alias getid="sed -e 's/[ |]*//' -e 's/ .*//'"

## Step 2. Upload a XenServer image

    glance image-create --name demoimage \
    --copy-from=https://github.com/downloads/citrix-openstack/warehouse/cirros-0.3.0-x86_64-disk.vhd.tgz \
    --container-format=ovf --disk-format=vhd

Wait until it is active, and get its id:

    IMGID=$(glance image-list | grep demoimage | getid)

## Step 2. Create a Volume

    cinder create --display_name="demovolume" --image-id=$IMGID 1

Wait until it is available, and get its id:

    VOLID=$(cinder list | grep "demovolume" | getid)

## Step 3. Upload as a qcow image

    cinder upload-to-image --container-format=bare --disk-format=qcow2 $VOLID uploaded_image

## Problem
The uploaded image is in vhd/ovf format, because

    glance image-list | grep uploaded_image

Prints:

    ... | vhd | ovf ...

    XenAPINFS: Fix Volume always uploaded as vhd/ovf

    Fixes bug 1131291

    copy_volume_to_image was always using the glance plugin to do the
    upload, and was ignoring the users request. Thus the image was always
    uploaded as vhd/ovf. This patch is using the image utils to fix the
    generic case.
