SOLR Docker image support S2I for core configs

This image supports restricted scc on Openshift and uses the S2I process to copy your SOLR core configs. – Prepare a GIT repository with your configs – Create a folder cores and place your cores there. The content of the cores folder will be copied into /opt/solr/server/solr. – oc new-app might have a problem identifying the build type. Though it’s not a java build, but just a plain copy, place an empty pom.xml into the root of your GIT repo. – A full template could be found in ose-artifacts/appagile-solr-standalone-template.json
