[s2i build] how to customize output image tag ?

Issue

• In xpaas example templates (eg. eap64-basic-s2i.json), the tag of output imagestream s2i buildConfiguration is always "latest".
  eg:

                "output": {
                    "to": {
                        "kind": "ImageStreamTag",
                        "name": "${APPLICATION_NAME}:latest"
                    }

In a template we can use a template parameter, but this parameter value will be hard-coded in the buildConfiguration, and will be the same for all build process.

How can we have another tag, which can be different on each build ?
For example, can we have a tag linked to version number of the application ?

Is there a way to push a parameter to a build process, parameter that can be used for the imagestream tag ?

• I made some tests with the Jenkins sample job .. and it shows real opportunities.
  I have to step back to build the full puzzle.

One more question : how can we use binary build/deploy through Jenkins ?
(how to do something like "oc start-build numberguess-bin --from-dir=/tmp/numberguess-bin")

• Using the oc command available within the jenkins image for binary builds, forces that these binary packages should be inside the jenkins pod/container ... not really satisfactory.
  Did I forget something else ?
