add static class api compatibility layer for pipeline .NET languages, like F#

[jkone27]

would be greate to have a way to configure .NET aspnecore by default also for F# projects,

so as an alternative of builder pattern and derivatives and fluent extensions (OO way), just pseudocode here

new Builder()
      .WithA(.....)
      .WithB(.....)
      .Build()
      .Configure(...)

also provide static methods from static classes constructing new objects and returning them as result

      var b = new Builder();
      var b2 = StaticModule.WithA(b)
      var b3 = StaticModule.WithB(b2)
      var app = Builder.Build(b3);
      return App.Configure(app);

so that in F# it can be used as

new Builder()
|> StaticModule.WithA
|> StaticModule.withB
|> Builder.Build
|> App.Configure

Later versions of F# let you do this (from memory; caveat emptor):

Builder()
|> _.WithA(...)
|> _.WithB(...)
|> _.Build()

This is never going to be as pretty/ergonomic as functions would be, but it's considerably better than the fluent APIs.
