Add UseIISPlatformHandler extension method to IWebApplicationBuilder

[davidfowl]

See aspnet/Hosting#553. Here's what the entry point would look like:

using System.IO;
using Microsoft.AspNet.Hosting;

namespace HelloMvc
{
    public class Program
    {
        public static void Main(string[] args)
        {
            var hostingConfiguration = WebApplicationConfiguration.GetDefault(args);

            var application = new WebApplicationBuilder()
                        .UseApplicationBasePath(Directory.GetCurrentDirectory())
                        .UseServerFactory("Microsoft.AspNet.Server.Kestrel")
                        .UseConfiguration(hostingConfiguration)
                        .UseUrls("http://localhost:5000")
                        .UseIISPlatformHandler()
                        .UseStartup<Startup>()
                        .Build();

            application.Run();
        }
    }
}

UseIISPlatformHandler sets the appropriate server.urls entry for the port and base path. These are baked into hosting today.

I assume this is part of the outcome from yesterdays hours of discussion?

If you call it UseIISPlatformHandler for both IWebApplicationBuilder and IApplicationBuilder it's going to be very confusing to document. How about UseIISPlatformHandlerUrl?

@Tratcher Is it safe to remain on a current runtime (-rc2-16357 at MyGet nightly) for this change with Hosting package(s) declared -rc2-*? In addition to the extension in Main, what needs to be done on the runtime/packaging dependencies side (if anything)?

[Tratcher]

Microsoft.AspNet.Hosting rc2-16219 and later. Microsoft.AspNet.IISIntegration rc2-16132 and later. You'll need to update both packages at the same time as there is a conflict between the new and old behavior.
It's hard to say what build of DNX works with specific versions of other packages without testing.

@Tratcher Thx. Apparently I've been ok with runtime dnx-coreclr-win-x64.1.0.0-rc2-16343, but I'll upgrade that later today. I've always had my packages set to -rc2-*, so I'm 🍰 on that.
