Updates to Azure DevOps and App Service improvements

In the sprint 157 update of Azure DevOps, we added rollup columns to backlogs that let you track progress across work item hierarchies (for example, epics/features/user stories). We also added multiple improvements for deploying Azure App Service apps. Take a look at the feature list below for more.
