Dockerfile Maven

At this point, we're not developing or accepting new features or even fixing non-critical bugs. This Maven plugin integrates Maven with Docker. Don't do anything fancy. Dockerfiles are how you build Docker projects; that's what this plugin uses. They are mandatory. Make the Docker build process integrate with the Maven build process. If you bind the default phases, when you type mvn package, you get a Docker image. When you type mvn deploy, your image gets pushed. Make the goals remember what you are doing. You can type mvn dockerfile:build and later mvn dockerfile:tag and later mvn dockerfile:push without problems. This also eliminates the need for something like mvn dockerfile:build -DalsoPush; instead you can just say mvn dockerfile:build dockerfile:push. Integrate with the Maven build reactor. You can depend on the Docker image of one project in another project, and Maven will build the projects in the correct order.
