Allow control of storage account DefaultServiceVersion through Azure Panel for true HTTP/1.1
By default, when a new Storage Account is created, the DefaultServiceVersion property is set to 2009-09-19, which is really old. Many storage accounts created now don't need backwards compatibility with this very old version.
It would be very useful to allow control of DefaultServiceVersion through Azure control panel or better, when creating a new Storage Account (same way you can select Windows release when creating VM) so that one can select it to a more recent version and thus allow storage account to respond to HTTP/1.1 Range request.
