/**
* A close relative of `retry`. This method wraps a task and makes it
* retryable, rather than immediately calling it with retries.
*
* @name retryable
* @static
* @memberOf async
* @see async.retry
* @category Control Flow
* @param {Object|number} [opts = {times: 5, interval: 0}| 5] - optional
* options, exactly the same as from `retry`
* @param {Function} task - the asynchronous function to wrap
* @returns {Functions} The wrapped function, which when invoked, will retry on
* an error, based on the parameters specified in `opts`.
* @example
*
* async.auto({
* dep1: async.retryable(3, getFromFlakyService),
* process: ["dep1", async.retryable(3, function (results, cb) {
* maybeProcessData(results.dep1, cb);
* })]
