* [HUDI-892] RealtimeParquetInputFormat skip adding projection columns if there are no log files
* [HUDI-892] for test
* [HUDI-892] fix bug generate array from split
* [HUDI-892] revert test log
1. Added the --clean-input and --clean-output parameters to clean the input and output directories before starting the job
2. Added the --delete-old-input parameter to deleted older batches for data already ingested. This helps keep number of redundant files low.
3. Added the --input-parallelism parameter to restrict the parallelism when generating input data. This helps keeping the number of generated input files low.
4. Added an option start_offset to Dag Nodes. Without ability to specify start offsets, data is generated into existing partitions. With start offset, DAG can control on which partition, the data is to be written.
5. Fixed generation of records for correct number of partitions
- In the existing implementation, the partition is chosen as a random long. This does not guarantee exact number of requested partitions to be created.
6. Changed variable blacklistedFields to be a Set as that is faster than List for membership checks.
7. Fixed integer division for Math.ceil. If two integers are divided, the result is not double unless one of the integer is casted to double.
* [HUDI-1326] Added an API to force publish metrics and flush them.
Using the added API, publish metrics after each level of the DAG completed in hudi-test-suite.
* Code cleanups

- config field is no longer transient in key generator
- verified that the key generator object is shipped from the driver to executors, just the one time and reused for each record
The current DFSPathSelector only ignore prefix(_, .) at the file level while files under subdirectories
e.g. (.checkpoint/*) are still considered which result in bad-format exception during reading.
- Update hudi-spark-bundle pom to not relocate hbase and htrace pattern
- Remove codec relocation as this is not included in bundle which was causing error
Remove APIs in `HoodieTestUtils`
- `createCommitFiles`
- `createDataFile`
- `createNewLogFile`
- `createCompactionRequest`
Migrated usages in `TestCleaner#testPendingCompactions`.
Also improved some API names in `HoodieTestTable`.
When the hbase index is used, when the record partition is changed to another partition, the path does not change according to the value of the partition column

1. Use the DAG Node's label from the yaml as its name instead of UUID names which are not descriptive when debugging issues from logs.
2. Fix CleanNode constructor which is not correctly implemented
3. When generating upsets, allows more granualar control over the number of inserts and upserts - zero or more inserts and upserts can be specified instead of always requiring both inserts and upserts.
4. Fixed generation of records of specific size
- The current code was using a class variable "shouldAddMore" which was reset to false after the first record generation causing subsequent records to be of minimum size.
- In this change, we pre-calculate the extra size of the complex fields. When generating records, for complex fields we read the field size from this map.
5. Refresh the timeline of the DeltaSync service before calling readFromSource. This ensures that only the newest generated data is read and data generated in the older Dag Nodes is ignored (as their AVRO files will have an older timestamp).
6. Making --workload-generator-classname an optional parameter as most probably the default will be used
This helps in removing reporter once the test has complete. Prevents log pollution from un-necessary metric logs.
- Added an API to shutdown the metrics reporter after tests.
- This change breaks `hudi-client` into `hudi-client-common` and `hudi-spark-client` modules
- Simple usages of Spark using jsc.parallelize() has been redone using EngineContext#map, EngineContext#flatMap etc
- Code changes in the PR, break classes into `BaseXYZ` parent classes with no spark dependencies living in `hudi-client-common`
- Classes on `hudi-spark-client` are named `SparkXYZ` extending the parent classes with all the Spark dependencies
- To simplify/cleanup, HoodieIndex#fetchRecordLocation has been removed and its usages in tests replaced with alternatives
