    Retry logic for url request in heat-config-notify

    Adds retry logic for software deployments using the url signals
    to ensure that requests are retried if network connection issues
    occur or a 500, 502, 503, or 504 is returned by the http or https
    endpoint.

    Note: this does not add retry logic to heatclient or zaqarclient
    if they are used for signaling.
