Description

While working on the YAML DSl, I've noticed that a route like:

- from: 
    uri: "direct:start"
    steps:    
      - saga:  
        propagation: "MANDATORY"
        completion-mode: "MANUAL"
        steps: 
        - to: "direct:something"
      - to: "mock:result"

Gets re-wired to be something like:

- from: 
    uri: "direct:start"
    steps:    
      - saga:  
        propagation: "MANDATORY"
        completion-mode: "MANUAL"
        steps: 
        - to: "mock:result"
        - to: "direct:something"

So in fact any output is moved to the saga outputs.

This happen because the saga is supposed to be a top level only feature and to be applied to the entire route (same for transacted).

The model should have a a separate definition for route configurations so you can configure saga, tx, onException et all there only and not later in the regular route
