EAP Quickstarts references removed templates.

The quickstarts for EAP 7.4 contains outdated instructions to import templates in OpenShift:

https://htmlpreview.github.io/?https://github.com/jboss-developer/jboss-eap-quickstarts/blob/7.4.x/kitchensink/README.html

The correct instructions are contained in the EAP 7.4 guide:

https://access.redhat.com/documentation/en-us/red_hat_jboss_enterprise_application_platform/7.4/html/getting_started_with_jboss_eap_for_openshift_container_platform/build_run_java_app_s2i#import_imagestreams_templates

The instructions must be updated in https://github.com/jbossas/eap-quickstarts/blob/7.4.x/shared-doc/openshift-import-imagestreams-templates.adoc.

I don't understand why the quickstarts duplicate product documentation instead of linking to it directly...
