Description

We can add support for letting property placeholders be optional, if the key starts with ?

eg so you can do

to("kafka:cheese?{{?maxBlock}}")

And maxBlock is a key=value

But for endpoints we should allow the value to indicate its optional which makes the option optional.

to("kafka:cheese?maxBlockMs={{?myBlock}}")

So the producer will then only use maxBlockMs if there is a value, otherwise the uri becomes "kafka:cheese"
