Creates a new future which will select over a list of futures.
The returned future will wait for any future within iter

completion the item resolved will be returned, along with the index of the
future that was ready and the list of all the remaining futures.
There are no guarantees provided on the order of the list with the remaining futures. They might be swapped around, reversed, or completely random.
