Double sided USB A cable is not new (article in Japanese, but check the pictures).

Neither is a "no data, fast charging" cable. As others have mentioned, it involves shorting some wires inside the cable

Both of these links are from 2012, though there is probably earlier stuff I didn't find. Regarding the second point, if you have the right wall wart, such as the one that comes included with the nexus 7 (I own one), then there is no need for a special USB cable to achieve 2A on devices that support it. The post I linked talks about car charging, which is obviously one application for a special cable.
Again, as others have mentioned, it is not possible to (safely) make your device draw more than the USB standard specifies, this cable won't change that.
