Description

The current JSON parser benchmark suite is fairly limited, as it only really tests objects with a couple non-varying fields. To properly measure optimizations based on input predictability (i.e. ARROW-4709) it would be beneficial to provide a parameterized way to create schemas with an arbitrary number of fields and add benchmarks for input with randomly ordered/omitted fields.
