Global options are not for storing arbitrary end user stuff really.
Its for some global options for Camel itself for some logging max
sizes, and some other bits.
That said the options are stored as key/values as-is and not evaluated
during routing of an exchange as they are not intended for that.
But if you want to do it anyway, then your process method can store
the body size as a value instead of a simple text.
Something ala .put("xxx", exchange.getMessage.getBody.size)
