Unfortunately spring property place holder cannot replace vars in camel
context tag, there is open issue for this:
https://issues.apache.org/activemq/browse/CAMEL-1066
Not sure if there is easy solution for this, but you can add custom
processor which will encapsulate your endpoint and than expose the property
on processor to be replaced by spring's PropertyPlaceHolderConfigurer.
