Kafka Configurator as an external library which can be called from Java code

[aaaleshaaa]

There are scenarios where is convenient to run Kafka Configurator as an external library from Java code. But there are some obstacles in that:

• Due to Scala/Java paradigm mismatch, there is no pretty way to process case classes in Java, the result of Kafka Configurator work is exactly that class.
• Calling of run(...).get() yields in Tuple2<List<ConfiguratorFailure>,List<String>> result type which cannot be processed from the outer code due to package restriction of ConfiguratorFailure class.

It would be nice to have:

• A dedicated function which result can be elegantly processed in Java code
• Positive results can be exposed as a List<String> as it returned in Tuple2 result of Scala code
• Negative results could be propagated as Exception class descendants (either Runtime one, or not)
• Scala provides a list of ConfiguratorFailure but it's enough to return to Java a Throwable instance got from the head of this list (if we have got sufficient logging on Scala side)

@mc-alesha thanks for raising the issue. I am on holiday this week, but we will be discussing the best way to proceed with this when I am back.
