    **Fixed** default retry policy to exclude retries on 503 which is potentially unsafe for idempotent requets.
    It can be reverted by setting "EXCLUDE_UNSAFE_503_FROM_DEFAULT_RETRY" to false. Please note that this flag is
    only available for backward compatibility reasons and will be removed in future releases.
