timeout overrides configured greater delay value

[justwrote]

After some debugging I found out that specifying the timeout (https://github.com/krasserm/streamz/blob/master/streamz-camel-akka/src/main/scala/streamz/camel/akka/EndpointConsumer.scala#L52) will override the config delay (http://camel.apache.org/file2.html). This only happens if the delay value is greater than your 500ms timeout. Since we need a greater value it would be nice to have it removed at all and use the receive(uri) method (delay seems to have the same effect) or at least make it possible to change it. If you wish I'm happy to create a PR.

Would appreciate a PR, thanks for offering. Maybe allowing applications to optionally place a config file (read by https://github.com/lightbend/config for example) would make most sense. Otherwise, several DSL methods would have to be extended in both, the camel-akka and camel-fs2, modules. Thoughts?
