Convert EAP CD application templates to use AMQ 7 for the external broker

Once the AMQ 7 image is released, move the EAP CD templates to use it.

Tasks:

1) Confirm that the AMQ 7 image will be non-TP in June.
2) Confirm with Bilge that using a TP AMQ 7 is ok in the TP EAP CD 13.
3) Validate that existing QS that assume the external broker work. (I think this is just jta_crash_req)
4) Confirm that QS that use JMS 2 work when the template that uses AMQ 7 is used instead of the eap-cd-basic-s21 template. More broadly confirm that JMS 2 works properly with the embedded broker installed.
5) Convert any remaining QS in jboss-developer/jboss-eap-quickstart to use JMS 2 and remove any xxx-jms.xml from the deployments.

This issue then becomes a pre-requisite for the JIRA to remove support for the embedded broker.
