retries for network errors (e.g. ECONNRESET)

[mfulton26]

sometimes Twilio calls fails for intermittent network/server errors (e.g. ECONNRESET); can the Auto-Retry with Exponential Backoff be updated or a similar option added to also retry under these conditions?

Lines 37 to 66 in 55db7c2

	function getExponentialBackoffResponseHandler(
	axios: AxiosInstance,
	opts: ExponentialBackoffResponseHandlerOptions

	const maxRetries = opts.maxRetries;
	return function (res: AxiosResponse<any, any>) {
	const config: BackoffAxiosRequestConfig = res.config;
	if (res.status !== 429) {
	return res;
	}
	const retryCount = (config.retryCount || 0) + 1;
	if (retryCount <= maxRetries) {
	config.retryCount = retryCount;
	const baseDelay = Math.min(
	maxIntervalMillis,
	DEFAULT_INITIAL_RETRY_INTERVAL_MILLIS * Math.pow(2, retryCount)
	);
