For Delete API, "hoodie.delete.shuffle.parallelism" isn't used as opposed to "hoodie.upsert.shuffle.parallelism" is used for upsert, this creates the performance difference between delete by upsert API with "EmptyHoodieRecordPayload" and delete API for certain cases.
This patch makes the following fixes in this regard.
- Let deduplicateKeys method use "hoodie.delete.shuffle.parallelism"
- Repartition inputRDD as "hoodie.delete.shuffle.parallelism" in case "hoodie.combine.before.delete=false"
- Generalize the hive-sync module for syncing to multiple metastores
- Added new options for datasource
- Added new command line for delta streamer

* [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
* Register avro schema if infered from SQL transformation
* Make HoodieWriteClient creation done lazily always. Handle setting schema-provider and avro-schemas correctly when using SQL transformer
