Improve story for setting-up logging outside of web/generic host

[pakrym]

It became harder after old style members were obsolete.

A possible solution is to add a wrapper method that would create container internally so what you'll see from outside would be:

LoggerFactory.Create(builder => builder
     .AddConsole()
    .AddFilter(...)
    .AddConfiguration(...));

This would require shipping a new package because we can't add a dependency on MEDI to Logging.Abstrations or Logging itself.

Whoops, wrong repo. Closing in favor of dotnet/extensions#615
