> For example we may want to do this route...
> {code}
> <route>
>   <requires>
>     <el>${broker2.queueSize('AnotherQueue') == 0}</el>
>   </requires>
>   <from uri="broker1:MyQueue"/>
>   <to uri="broker2:AnotherQueue"/>
> </route>
> {code}
> i.e. only implement a specific route while some predicate is true (e.g. only route while a condition is met; disable when its not met).
> Maybe we need to allow endpoints to define if they are ready yet? e.g. only send to a certain queue if its got capacity?
