Added a profile to create a docker image on the latest code

run mvn clean install -P docker. You'll have a docker image that can be run with:

````
docker run -it --rm -p 8080:8080 -p 9990:9990 apiman-distro-wildfly8:1.0.1-SNAPSHOT
````

This is using this plugin, and can be enhanced, worked with: https://github.com/spotify/docker-maven-plugin 
I've tried different plugins, and this is the one that best fits this needs.
