73 openshift crashes slightly less often (project-koku#109)

* Added sleep to cluster up and a reinit feature to the Makefile that makes the project without a cluster down/up cycle * Added troubleshooting for OpenShift docker to openshift.rst * Gave the DB it's own secret and modified db name

+Troubleshooting
+---------------
+
+OpenShift uses Docker to run containers. When running a cluster locally for developement, deployment can be strained by low resource allowances in Docker. For development it is recommended that Docker have at least 4 GB of memory available for use.
+
+Also, if Openshift services misbehave or do not deploy properly, it can be useful to spin the cluster down, restart the Docker service and retry.
