        Initialize a `Retry` object with a `Backoff` object
        that retries a maximum of `retries` times.
        `retries` can be negative to retry forever.
        You can specify the types of supported errors which trigger
        a retry with the `supported_errors` parameter.

        Execute an operation that might fail and returns its result, or
        raise the exception that was thrown depending on the `Backoff` object.
        `do`: the operation to call. Expects no argument.
        `fail`: the failure handler, expects the last error that was thrown
