    execute: don't call greenthread.sleep directly

    The module may be used in scope that is not using eventlet (f.e. from
    inside neutron-keepalived-state-change), in which case a call to
    greenthread.sleep from the main thread will result in AssertionError.

    Instead of that, call time.sleep that will redirect to greenthread.sleep
    in eventlet environment.

    This reflects what we do in oslo.concurrency execute implementation.
