/**
 * Applies the provided arguments to each function in the array, calling
 * `callback` after all functions have completed. If you only provide the first
 * argument, `fns`, then it will return a function which lets you pass in the
 * arguments as if it were a single function call. If more arguments are
 * provided, `callback` is required while `args` is still optional. The results
 * for each of the applied async functions are passed to the final callback
 * as an array.

 * @param {Array|Iterable|AsyncIterable|Object} fns - A collection of {@link AsyncFunction}s
 * to all call with the same arguments
 * @param {...*} [args] - any number of separate arguments to pass to the
 * function.
 * @param {Function} [callback] - the final argument should be the callback,
 * called when all functions have completed processing.
 * @returns {AsyncFunction} - Returns a function that takes no args other than
 * an optional callback, that is the result of applying the `args` to each
 * of the functions.
 * @example
 *
 * const appliedFn = async.applyEach([enableSearch, updateSchema], 'bucket')
 *
 * appliedFn((err, results) => {
 *     // results[0] is the results for `enableSearch`
 *     // results[1] is the results for `updateSchema`
 * });
 *
 * // partial application example:
 * async.each(
 *     buckets,
 *     async (bucket) => async.applyEach([enableSearch, updateSchema], bucket)(),
 *     callback
 * );
