Make IHttpOutputAborter public

[maruyama-tomo]

Background and Motivation

When there are cache servers (nginx, varnish, etc) in front of ASP.NET Core, and responding chunked body, we can tell them not to cache the response by aborting the output.
It is useful if retriable errors may occur while generating length-unknown chunked responses.

Proposed API

-internal interface IHttpOutputAborter
+public interface IHttpOutputAborter

Usage Examples

response.HttpContext.Features.Get<IHttpOutputAborter>()?.Abort(exception);

// currently, we are using above via reflection
//
// var aborter = response.HttpContext.Features.GetType().GetInterface("IHttpOutputAborter");
// aborter?.GetMethod("Abort")?.Invoke(response.HttpContext.Features, new[] { exception });

Alternative Designs

Porting System.Web's HttpResponse.Close() method also would be nice.

Risks

I don't think any risk so far.
