- remove useless `configuration` variables and `Configuration` instances
- remove "Review" code comment
- unintentionally included in commit 4b5dd19
- reduce repeated code in `TestHelper` for functional tests
- `CreateServer()` methods had duplicate code, an ambiguous match, and an odd order
- rename `GetTestConfiguration()` to `UseCultureReplacer()` in functional tests
Adding dependencies and commands for iis, web listener and khestrel to each

Once VS sees a project with a wwwroot, it wants to assign a port for iis,
so I let it.
