When a Petals Exchange goes into a Camel route from the Petals NMR, a newly created Camel Exchange could get some of the properties copied from the Petals Exchange.
The properties will be prefixed by prefixed by "PetalsOriginalProperty." (see also PETALSSECAMEL-16).
Inversely, when the answer comes back as a Camel exchange and is sent back into the NMR, then the Petals Exchange properties are updated with those of the Camel Exchange still prefxed by "PetalsOriginalProperty.".
