Adding servers and wwwroot folder to test websites

Adding dependencies and commands for iis, web listener and khestrel to each
site.

Each website comes with a readme.md to 'anchor' the otherwise empty
folder. We have another work item tracking adding content to these.

Once VS sees a project with a wwwroot, it wants to assign a port for iis,
so I let it.
Update names of WebSite projects for consistency

Project/Assembly names are all like 'FeatureWebSite' root namespaces
updated accordingly. This makes processing all of the functional tests and
deploying the web sites much simpler.
