title: ARM - How can I get the access key from a storage account to use in AppSettings later in the template?
body: <p>I'm creating an Azure Resource Manager template that instantiates multiple resources, including an Azure storage account and an Azure App Service with a Web App.</p>
  
  <p>I'd like to be able to capture the primary access key (or the full connection string, either way is fine) from the newly-created storage account, and use that as a value for one of the AppSettings for the Web App.</p>
  
  <p>Is that possible?</p>
