* Remove the metadata cleaning strategy for flink, that means the multi-modal index may be affected
* Improve the HoodieTable#clearMetadataTablePartitionsConfig to only update table config when necessary
* Remove the modification of read code path in HoodieTableConfig
No need to #sync actively because the table instance is instantiated freshly,
its view manager has empty fiew instantces, the fs view would be synced lazily when
is it requested.
- getDataSize has non-trivial overhead in the current ParquetWriter impl, requiring traversal of already composed Column Groups in memory. Instead we can sample these calls to getDataSize to amortize its cost.

- Avoid using udf for key generator for SimpleKeyGen and NonPartitionedKeyGen.
- Fixed NonPartitioned Key generator to directly fetch record key from row rather than involving GenericRecord.
- Other minor fixes around using static values instead of looking up hashmap.
- Due to the fact that Spark 3.2.1 is non-BWC w/ 3.2.0, we have to handle all these incompatibilities in Spark32HoodieParquetFileFormat. This PR is addressing that.

- when columns names are renamed (schema evolution enabled), while copying records from old data file with HoodieMergeHande, renamed columns wasn't handled well.
- Scaffolded `Spark24HoodieParquetFileFormat` extending `ParquetFileFormat` and overriding the behavior of adding partition columns to every row
- Amended `SparkAdapter`s `createHoodieParquetFileFormat` API to be able to configure whether to append partition values or not
- Fallback to append partition values in cases when the source columns are not persisted in data-file
- Fixing HoodieBaseRelation incorrectly handling mandatory columns
Fixing FILENAME_METADATA_FIELD not being correctly updated in HoodieMergeHandle, in cases when old-record is carried over from existing file as is.
- Revisited HoodieFileWriter API to accept HoodieKey instead of HoodieRecord
- Fixed FILENAME_METADATA_FIELD not being overridden in cases when simply old record is carried over
- Exposing standard JVM's debugger ports in Docker setup
* Fixing incorrect selection of MT partitions to be updated
* Ensure that metadata partitions table config is inherited correctly

* Filter out empty string (for non-partitioned table) being added to "__all_partitions__" record
* Instead of filtering, transform empty partition-id to `NON_PARTITIONED_NAME`
* Cleaned up `HoodieBackedTableMetadataWriter`
* Make sure REPLACE_COMMITS are handled as well
- Adding capability to fetch Metadata Records by key prefix so that Data Skipping could fetch only Column Stats
- Index records pertaining to the columns being queried by, instead of reading out whole Index.
- Fixed usages of HFileScanner in HFileReader. few code paths uses cached scanner if available. Other code paths uses its own HFileScanner w/ positional read.
Brief change log
- Rebasing ColumnStatsIndexSupport to rely on HoodieBackedTableMetadata in lieu of reading t/h Spark DS
- Adding methods enabling key-prefix lookups to HoodiFileReader, HoodieHFileReader
- Wiring key-prefix lookup t/h LogRecordScanner impls
- Cleaning up HoodieHFileReader impl
