Avoid unnecessary serialization between Camel routes

[brosenberg42]

Whenever an object needs to be sent from one route to another or between processors in a single route, it gets serialized in the Smile format. The objects are only used within the WFM JVM so serialization is unnecessary.

As an alternative to serialization, we should consider avoiding multiple Camel processors for functionality that is all performed by the WFM - this may be accomplished using method calls instead.
