Updates for OpenShift 4 (OCP4) Deployment

[DerekRoberts]

Updates:

• ./openshift/config.env - APP, NAMESPACE_TOOLS, NAMESPACE_DEPLOY, DOMAIN and DOCKER_SRC
• ./openshift/rollout.sh - GIT_BRANCH override for testing from forks (still getting code from primary URL)

Note: Aporetto requires some extra steps to configure network security policies. Since this service is being discontinued code for it was not included. The workaround is below. The linked template may not hang around either.
