Azure Stack Marketplace Management

Been doing some work with Azure Stack and wanted to easily update all the Microsoft provided extensions and a set of core images if there are new versions by running a simple script.

Script available at https://github.com/johnthebrit/AzureStack/blob/master/azurestackmarketplace.ps1. Simply run the script and after it downloads the assets it will check if there are older versions and prompt you if you want to delete the old ones.
