@rsrkpatwari1234 why do we need it in BaseRecordExtractor and not in
ParquetNativeRecordReader / ParquetAvroRecordReader ?
The generic handling of "element" in BaseRecordExtractor seems like a hack
and will not be applicable if the data itself is of the form
```
"metadata": {"tags":[{"element":"abc"}, {"element":"xyz"}]}
```
Additionally, the change (in any reader) will mean backward incompatibility
for queries if they're already querying with existing data structure. I am not
sure if thats ok to proceed or not @Jackie-Jiang . Or if we need to put the
change behind a flag.
