Official nuget package for dotnet new

Now when we have [wiki](https://github.com/Azure/azure-functions-templates/wiki/Using-the-templates-directly-via-dotnet-new) on how to create Functions with `dotnet new`, I have some questions:

1. Why are they split into 2 packages (project / functions)?
2. When will it become an official NuGet package to install without downloads from MyGet? Will it be just 1 package?
3. Should F# functions go to the same package(s) or separate one(s)?

Start with the linked wiki page on using the templates via dotnet new, then review the questions about the project and functions packages, MyGet distribution, and F# functions. Done means reaching a maintainer decision on the official NuGet packaging structure and supported F# package arrangement.
