Dead end the Microsoft.Extensions.Configuration.NewtonsoftJson package

[Anipik]

Fixes #3816

• removing the Microsoft.Extensions.Configuration.NewtonsoftJson package
• updating the preview label 3 (just for consistency, we wont be shipping any packages from here)
• updating the readme file
• It doesnt seem like we are using this package anywhere in our build.

Just to make sure, did you get sign-off from the library owner's to remove it?

I think runtime team is supposed to own this package and i dont think we have any person assigned as owner for this one.

Why are we doing this?

@davidfowl - more reasoning than what is listed in #3816:

1. This is the only remaining "shipping" package in dotnet/extensions. This will allow us to no longer build/maintain the dotnet/extensions repo in the main branch.
2. We moved the rest of the packages either to dotnet/aspnetcore or dotnet/runtime. Moving this one to dotnet/runtime will make a "product dependency" from dotnet/runtime to Newtonsoft.Json, which isn't ideal. dotnet/rutnime is supposed to be the "bottom of the stack".

So unless we can find another home for this package (which only has 42k total downloads in 2 years), it doesn't warrant the maintenance burden.

Is there some unique benefit this package provides that https://www.nuget.org/packages/Microsoft.Extensions.Configuration.Json/ doesn't?

Why is this getting mvoed to 3 now (vs. when we branch?)

[Anipik]

I just combined the changes together, we wont be building or shipping anything from this.

[mmitche]

Is it being retired going forward? Or will there be things for preview 3?

[Anipik]

its being retired going forward. we dont want to ship anything in preview2 as well from extensions repo.

Got it, if we don't see the value nor the usage then I'm ok with it.
