Preprocessor should test topic to ensure enough partitions exist

[bryanlb]

Description

Today if you attempt to connect a preprocessor to a kafka topic, and configure it to more output partitions than exist on the kafka topic it is difficult to detect. This ends up throwing a significant amount of confusing messages as it still attempts to register a stream application with an invalid config.

The preprocessor should test the validity of a dataset config (possibly using admin client) and alert the user if it detects something that cannot be satisfied.
