GH-881 - Support for SpEL expression in routing targets.

Browse Source 
We now support SpEL expressions in routing targets for events to be externalized. Introduced a BrokerRouting.getTarget(Object) overload to allow access to the event object in the SpEL expression. To support those, event externalizers will have to call that method where they previously called ….getTarget().
