docker compose: multi-service orchestration example

Example that will contain

• two tomcat applications with source code, Maven projects (application 1 calls application 2)
• both applications use JAX-RS i.e are RESTful web services
• Dockerfiles for each that will package these into self contained docker images based on tomcat base image.
• Docker Compose file to tie everything up
