When commands like dotnet nuget push or dotnet nuget config, dotnet list package today are invoked, the .NET SDK's dotnet.exe process has it's own parsing, which later gets forwarded to a completely new runnable, NuGet.Commandline.Xplat, which pretty much duplicates all the arguments.

This leads to an unnecessary 2nd process, difficulty debugging, + lots of duplicate work.

The proposal here is to change this integration to a compile time one, where the SDK just calls methods of NuGet.Commandline.Xplat instead of shelling out to a completely new process.
