Doc updates needed: 
1. In the overview section - update Maven v3.5 image to Maven v3.6 image?  * To update the link here we need the Maven v3.6 folder here, which I don't see as yet.

2. In the Images section -  
update the Rhel and CoreOS 7 images from :
`$ docker pull registry.redhat.io/openshift3/jenkins-agent-maven-35-rhel7` to `$ docker pull registry.redhat.io/openshift3/jenkins-agent-maven-36<should this be 3.6?>-rhel7`
and `$ docker pull openshift/jenkins-agent-maven-35-centos7` to `$ docker pull openshift/jenkins-agent-maven-36<should this be 3.6?>-centos7`

3. The RN updates, based on this input "Docs or a KCS article needs to be added to guide customers on how to build their own Jenkins agent image for Maven 3.6 and clarify the scope of support." need to be on these lines: 
https://docs.openshift.com/container-platform/3.11/release_notes/ocp_3_11_release_notes.html#ocp-3-11-232-features
(Siamak:  instead of Node.js, it will be the Maven image. No KCS article needed in this case and release note is fine.)
