There is a limit to how long input data can be for the heat script hook. It turns out that data longer than 131072, will return an Argument list to long error. To get around this, we need to pass this data in a different way so that the heat script hook will work. Change-Id: Ie3bd17ca9863e7687721e8c2628e485ea1849321 Closes-Bug: #1772071
