configure kamon logger to conform to rest of log messages

inspect controller logs and you'll find:

```
[INFO] [11/26/2017 15:33:12.339] [main] [StatsDExtension(akka://kamon)] Starting the Kamon(StatsD) extension
```
@mhenke1

Start by inspecting the controller logs and the configuration or entry point for the Kamon StatsD extension, which emits the shown message. Compare its format with the surrounding log messages; the work is done when the Kamon logger output conforms to the rest of the controller logs.
