- Adding ability to use native spark row writing for bulk_insert
- Controlled by `ENABLE_ROW_WRITER_OPT_KEY` datasource write option
- Introduced KeyGeneratorInterface in hudi-client, moved KeyGenerator back to hudi-spark
- Simplified the new API additions to just two new methods : getRecordKey(row), getPartitionPath(row)
- Fixed all built-in key generators with new APIs
- Made the field position map lazily created upon the first call to row based apis
- Implemented native row based key generators for CustomKeyGenerator
- Fixed all the tests, with these new APIs

- This pull request adds upgrade/downgrade infra for smooth transition from list based rollback to marker based rollback*
- A new property called hoodie.table.version is added to hoodie.properties file as part of this. Whenever hoodie is launched with newer table version i.e 1(or moving from pre 0.6.0 to 0.6.0), an upgrade step will be executed automatically to adhere to marker based rollback.*
- This automatic upgrade step will happen just once per dataset as the hoodie.table.version will be updated in property file after upgrade is completed once*
- Similarly, a command line tool for Downgrading is added if incase some user wants to downgrade hoodie from table version 1 to 0 or move from hoodie 0.6.0 to pre 0.6.0*
- *Added UpgradeDowngrade to assist in upgrading or downgrading hoodie table*
- *Added Interfaces for upgrade and downgrade and concrete implementations for upgrading from 0 to 1 and downgrading from 1 to 0.*
- *Made some changes to ListingBasedRollbackHelper to expose just rollback stats w/o performing actual rollback, which will be consumed by Upgrade infra*
- Reworking failure handling for upgrade/downgrade
- Changed tests accordingly, added one test around left over cleanup
- New tables now write table version into hoodie.properties
- Clean up code naming, abstractions.

* [HUDI-839] Introducing rollback strategy using marker files
- Adds a new mechanism for rollbacks where it's based on the marker files generated during the write
- Consequently, marker file/dir deletion now happens post commit, instead of during finalize
- Marker files are also generated for AppendHandle, making it consistent throughout the write path
- Until upgrade-downgrade mechanism can upgrade non-marker based inflight writes to marker based, this should only be turned on for new datasets.
- Added marker dir deletion after successful commit/rollback, individual files are not deleted during finalize
- Fail safe for deleting marker directories, now during timeline archival process
- Added check to ensure completed instants are not rolled back using marker based strategy. This will be incorrect
- Reworked tests to rollback inflight instants, instead of completed instants whenever necessary
- Added an unit test for MarkerBasedRollbackStrategy

Notable changes:
1. HoodieFileWriter and HoodieFileReader abstractions for writer/reader side of a base file format
2. HoodieDataBlock abstraction for creation specific data blocks for base file formats. (e.g. Parquet has HoodieAvroDataBlock)
3. All hardocded references to Parquet / Parquet based classes have been abstracted to call methods which accept a base file format
4. HiveSyncTool accepts the base file format as a CLI parameter
5. HoodieDeltaStreamer accepts the base file format as a CLI parameter
6. HoodieSparkSqlWriter accepts the base file format as a parameter
