Manoj Govindassamy bf4e3d63e7 [HUDI-3141] Metadata merged log record reader - avoiding NullPointerException when records by keys (#4505) ...

- HoodieMetadataMergedLogRecordReader#getRecordsByKeys() and its parent class methods
   are not thread safe. When multiple queries come in for gettting log records
   by keys, they all operate on the same log record reader instance provided by
   HoodieBackedTableMetadata#openReadersIfNeeded() and they trip over each other
   as they clear/put/get the same class memeber records.

 - The fix is to streamline the mutatation to class member records. Making
   HoodieMetadataMergedLogRecordReader#getRecordsByKeys() a synchronized method
to avoid concurrent log records readers getting into NPE.
