commit 166ac7869fbef4bc88ee5d26e72c7e01d5e581e2

    Increase interface detach polling period
    
    The gate has started failing due to interface detaches timing out.
    Examining the logs, it looks like Nova's interface detach retry takes about
    6s to run one attempt. Heat, on the other hand, does 10 retries at 0.5s
    intervals. So if Nova has to retry then Heat will fail.
    
    Increase Heat's polling interval to make it more likely that if Nova
    succeeds, Heat will see it.
