What changes were proposed in this pull request?
Add a new JSON write option sortKeys. When enabled, map keys are shown in lexicographical order.
Why are the changes needed?
Currently to_json() doesn't support the sort options, which makes comparing JSON strings from MapType inconvenient.
Does this PR introduce any user-facing change?
Yes. if setting as true, JSON object keys are sorted alphabetically. If "false", it works in default.
How was this patch tested?
Add unit tests in JacksonGeneratorSuite, JsonFunctionsSuite, PySpark tests in test_functions.py.
