getTopology returns the compiled topology after nimbus has gotten its hands on
it, so it has the ackers in it and the metrics consumers. getUserTopology
returns the topology as the user submitted it.

What is the difference between both? I don't understand what the
difference between a "(regular?) topology" and a "user topology" should
be... From my understanding, there is only one "type" of topologies.
Thanks for you help!
