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.
These tests verify that per-request services can be injected into assets
that users provide/implements (filters, constraints, controllers, views,
etc).
The purpose is to verify that the services are correctly resolved from the
per-request service container, and don't have state that lingers and
influences the next request. This is important because changing the
lifetime of a framework services could easily impact the lifetimes of
others, and ultimately of something the user created.
