Create new CamelWIH to integrate with recently added Camel support in jBPM/KIE-Server

The new camel-jbpm component allows CamelContexts and Routes to be defined on both a global (KIE-Server) and runtimeManager/deploymentUnit/KJAR level. A new CamelWorkItemHandler that integrates with these CamelContexts and routes would allow easy integration with external resources throuch Camel Components from within a process/case definition.
