IMPALA-12238: RandomNestedDataGenerator should take a seed argument
RandomNestedDataGenerator can be used to produce parquet files with
random data from Avro schemas. This change makes it possible to provide
a seed value for the random generator so the generated files are
reproducible. The seed can be given as the last (optional) command line
argument. It is parsed as a Java 'long'.
Testing:
- manually verified that when run with the same arguments (including
the seed), the data generator produces the same results
