This simplifies the way that we publish files to our network drop share.
Changes:
* Instead of explicitly listing every file that needs to publish, use directories to classify packages and artifacts into different categories.
* Add documentation for the expected layout of artifacts/
* Remove the need for static analysis to determine which packages go to which project
* Add the MSBuild property "IsProductPackage" to .csproj files which ship as a package to NuGet.org.
- Stop producing the 'Universe' lineup package
- Removes all PackageLineup code
- Use full msbuild on Windows
- Fix invalid reference to internal.aspnetcore.sdk in 2.1.x
- Fix shared folder references for PackageArchive task.
