> We can add support for letting property placeholders be optional, if the key starts with ?
> eg so you can do
> {code}
> to("kafka:cheese?{{?maxBlock}}")
> {code}
> And maxBlock is a key=value
> But for endpoints we should allow the value to indicate its optional which makes the option optional.
> {code}
> to("kafka:cheese?maxBlockMs={{?myBlock}}")
> {code}
> So the producer will then only use maxBlockMs if there is a value, otherwise the uri becomes "kafka:cheese"
