Create docker images with mono-runtime and xsp

The base image is built from a minimal (slim) debian 9 (stretch) with mono-runtime.

The mono-xsp4 images adds XSP to the base image and is ready to run an ASP.NET application with the XSP web server.

Simply map the port 80 to the port you want to use and share your published application to the /app folder.

docker run -p 8080:80 -v <path to my web app>:/app hpgy/mono-xsp4
