    Fix bug Swift ACL which disappears on Glance v1 images

    Currently, when we make an update on a public image, Swift ACL disappears.
    This patch allows to avoid the ACL update if there is no change to the
    is_public_attribute.
    If an update is made on a Glance image without changing the public attribute
    or location, then the function which modifies ACLS is not called, in order
    to keep ACLS.
