In general, for each resource that you would like to offer to your tenants, you could set up your own ARM template and deploy it to your tenants. This is a little complex, but you can make sure everything is configured to a 100%, just like you want it.

To make life easier, Azure Stack will provide an Azure Stack syndication with Azure Marketplace. This means that you can select and completely deploy an Azure offering to your Azure Stack data center and run it directly in your environment.
