[catboost4j-spark] The earlyStoppingRounds parameter is not recognized

[candalfigomoro]

Problem:
With PySpark, when I set the earlyStoppingRounds parameter (e.g. earlyStoppingRounds=10), I get the following error:

py4j.protocol.Py4JJavaError: An error occurred while calling o318.fit.
: ai.catboost.CatBoostError: catboost/private/libs/options/plain_options_helper.cpp:495: Unknown option {early_stopping_rounds} with value "10"

@andrey-khropov I have encountered the same issue that earlyStoppingRounds is not recognized in Spark Scala.
