Asciidoc READMEs in OpenShift branch don't contain OpenShift related information

The READMEs for all quickstarts, as well as the root README, in repository https://github.com/jboss-developer/jboss-eap-quickstarts/tree/openshift, lack descriptions related to OpenShift. I am aware that the .html versions do contain information on OpenShift, but that should be replicated to .adoc READMEs.

Additionally, many of the links in these READMEs are also dead, because they reference a nonexistent shared-doc directory.
