Description

Spouts and Bolt are initialized by a call to `Spout.open(...)` and `Bolt.prepare()`, respectively. Both methods have a config `Map` as first parameter. This map is currently not populated. Thus, Spouts and Bolts cannot be configure with user defined parameters. In order to support this feature, spout and bolt wrapper classes need to be extended to create a proper `Map` object. Furthermore, the clients need to be extended to take a `Map`, translate it into a Flink `Configuration` that is forwarded to the wrappers for proper initialization of the map.
