DRILL-8506: Ignore JSON Elements with Empty Keys
Description
If Drill encounters a JSON field with an empty key, currently Drill throws an exception. This behavior prevents Drill from reading the rest of the data. This PR modifies Drill's behavior by simply ignoring JSON data with empty keys. Drill will generate a log warning message when this happens.
Documentation
No significant user facing changes.
Testing
Ran existing unit tests.
