The app type. Each supported type is associated with a particular layer. For example, PHP applications are
associated with a PHP layer. OpsWorks Stacks deploys an application to those instances that are members of the
corresponding layer. If your app isn't one of the standard types, or you prefer to implement your own Deploy
recipes, specify <code>other</code>.
