SRAMP-561  Support Fuse JMS

https://issues.jboss.org/browse/SRAMP-561
I see where you were going with this, but I'd probably split it up into 2 different properties.  Note that they'd be mutually exclusive:

sramp.config.events.jms.embedded-activemq-port: used purely for the embedded broker, if needed
sramp.config.events.jms.activemq-url: used purely for Fuse/Fabric/Karaf installations where ActiveMQ is available
