    Add identity headers while calling glanceclient

    Glance and glanceclient have patches up for a no auth
    option in glance. In order for that to happen, nova needs to
    send in additional information in its headers to glanceclient.
    More details:
    Some deployments have everything in the same network. And
    for long running snapshots this may cause 401s because
    token expires. In these cases the reauth is not required
    cause nova has already authenticated the user.
    This patch does not convert it to no auth. It only makes
    it optional for glance users who do want to use that option.
