/**
* A close relative of [`retry`]{@link module:ControlFlow.retry}. This method
* wraps a task and makes it retryable, rather than immediately calling it
* with retries.
*
* @name retryable
* @static
* @memberOf module:ControlFlow
* @method
* @see [async.retry]{@link module:ControlFlow.retry}
* @category Control Flow
* @param {Object|number} [opts = {times: 5, interval: 0}| 5] - optional
* options, exactly the same as from `retry`, except for a `opts.arity` that
* is the arity of the `task` function, defaulting to `task.length`
* @param {AsyncFunction} task - the asynchronous function to wrap.
* This function will be passed any arguments passed to the returned wrapper.
* Invoked with (...args, callback).
* @returns {AsyncFunction} The wrapped function, which when invoked, will
* retry on an error, based on the parameters specified in `opts`.
* This function will accept the same parameters as `task`.
* @example
*
* async.auto({
* dep1: async.retryable(3, getFromFlakyService),
* process: ["dep1", async.retryable(3, function (results, cb) {
* maybeProcessData(results.dep1, cb);
* })]
* }, callback);
