    Race condition in keystone domain config

    This bug fixes a race condition in the domains_config
    decorator. The race condition occurs when more than
    one thread accesses the decorator. The first thread
    sets the configured flag to True before proceeding with
    driver load leading the second thread to use the default
    driver. This fix ensures that the second thread waits for
    the first thread to finish configuration before it uses
    the driver.
