URL: https://github.com/apache/hudi/pull/6782
### Change Logs
Currently, `HoodieMetadataLogRecordReader` is flushing cache for every
lookup it's doing, which led to multiple occasions of poor performance as MT
had to be re-scanned over and over again, even though nothing really changed.
This PR rectifies that, additionally
- Making sure `LogRecordScanner` is not extended for MT (there's no reason
for that, instead its configuration is simply expanded to accommodate for MT
use-case)
- Refining and cleaning up the API provided `HoodieMetadataLogRecordReader`
- Avoiding unnecessary locking
