* Deprecate the Microsoft.AspNetCore.App metapackage in favor of targeting and runtime packs
* Stop producing Microsoft.AspNetCore.App, and runtime.$(rid).Microsoft.AspNetCore.App
* Generate the shared framework without using 'NuGet' restore
* Stop producing intermediate packages for shared-framework only assemblies
* Put the platform manifest into the targeting pack (data/Microsoft.AspNetCore.App.PlatformManifest.txt)
* Create well-known, shared intermediate directories that installers can use to bundle content
This creates 3 new build outputs:
* aspnetcore-targeting-pack-$(version).tar.gz
* aspnetcore-targeting-pack-$(version)-linux-x64.deb
* aspnetcore-targeting-pack-$(version)-linux-x64.rpm
Other changes:
* Make RPM packaging consistent with other installers. Vendor == Microsoft Corporation
* Add shared properties for building the targeting pack (or not building it in a servicing build)
