This method PUT to update a creative.
Notes:

• When you update your creative, its creative approval status is reset to pending if the seller requires creative review. It is recommended that you only update creatives when absolutely necessary and that you inform the seller prior to doing so.
• FreeWheel currently supports a maximum of 30 creative renditions per VAST creative at one query per second for both POST and PUT methods. To improve performance, if possible, keep creative renditions to fewer than ten.
