    Add cinder_cross_az_attach option

    fixes bug 1128546

    This patch adds the cinder_cross_az_attach option to toggle
    whether volume attachments are allowed between zones, which was
    added in Grizzly.

    Given the current state of cinder and availability zone documentation
    this patch might be a little worthless. However, at least it will
    allow understanding of the default behaviour.

    Fix minor typo and spelling error.
