Connecting OAI enabled Fcrepo with Jupiter Docker environment

[jefferya]

In order to test the OAI enabled Frcrepo within the Jupiter Docker environment, I've forked a copy of murny/docker-fcrepo4 to https://hub.docker.com/r/jefferya/docker-fcrepo4/. The branch 4.7.4, contains the required changes to the 4.7/Dockerfile to enable the OAI Provider. This Dockerfile is built on DockerHub. The Jupiter, docker-compose.yml, line 37 determines the DockerHub image to download during the setup of the Docker containers and Jupiter Docker environment.

At present, a fork of the murny/docker-fcrepo4 repo:

• [x] alter Jupiter to pass credentials to Fcrepo/Tomcat
• [x] alter (OAI Fcrepo Dockerfile](https://github.com/jefferya/docker-fcrepo4/blob/4.7.4/4.7/Dockerfile) to a store the credentials example. Also, rebuild the DockerHub
• [ ] move code and images to UAL GitHub and DockerHub respectively
