Description
The MongoMK currently has multiple constructors, and it's likely that more config parameters will be added (some of them to simplify testing). Instead of adding even more constructors, a builder (factory) with a fluent API would be nice. Example usage:
MongoMK mk = new MongoMK.Builder().
setMongoDB(db).
setClusterId(clusterId).
setAsyncDelay(10).
open();
