So if you have a custom error message you just set the HTTP error code
to a value 300+ and rest-dsl will not do output binding. There is a
new option that is turned on by default, you can turn it off to use
the old behavior.

And the rest-dsl documentation has a little example in the bottom
https://cwiki.apache.org/confluence/display/CAMEL/Rest+DSL
