Refactoring layout optimization (clustering) flow to
- Enable support for linear (lexicographic) ordering as one of the ordering strategies (along w/ Z-order, Hilbert)
- Reconcile Layout Optimization and Clustering configuration to be more congruent
To modify SQL statement for creating hudi table based on an existing hudi path.
From:
```sql
create table hudi_tbl using hudi tblproperties (primaryKey='id', preCombineField='ts', type='cow') partitioned by (pt) location '/path/to/hudi'
```
To:
```sql
create table hudi_tbl using hudi location '/path/to/hudi'
```
* Introduce hudi-spark3-common and hudi-spark2-common modules to place classes that would be reused in different spark versions, also introduce hudi-spark3.1.x to support spark 3.1.x.
* Introduce hudi format under hudi-spark2, hudi-spark3, hudi-spark3.1.x modules and change the hudi format in original hudi-spark module to hudi_v1 format.
* Manually tested on Spark 3.1.2 and Spark 3.2.0 SQL.
* Added a README.md file under hudi-spark-datasource module.
* [HUDI-2909] Handle logical type in TimestampBasedKeyGenerator
Timestampbased key generator was returning diff values for row writer and non row writer path. this patch fixes it and is guarded by a config flag (`hoodie.datasource.write.keygenerator.consistent.logical.timestamp.enabled`)
* [HUDI-2154] Add index key field to HoodieKey
* [HUDI-2157] Add the bucket index and its read/write implemention of Spark engine.
* revert HUDI-2154 add index key field to HoodieKey
* fix all comments and introduce a new tricky way to get index key at runtime
support double insert for bucket index
* revert spark read optimizer based on bucket index
* add the storage layout
* index tag, hash function and add ut
* fix ut
* address partial comments
* Code review feedback
* add layout config and docs
* fix ut
* rename hoodie.layout and rebase master

Main functions:
Support create table for hoodie.
Support CTAS.
Support Insert for hoodie. Including dynamic partition and static partition insert.
Support MergeInto for hoodie.
Support DELETE
Support UPDATE
Both support spark2 & spark3 based on DataSourceV1.
Main changes:
Add sql parser for spark2.
Add HoodieAnalysis for sql resolve and logical plan rewrite.
Add commands implementation for CREATE TABLE、INSERT、MERGE INTO & CTAS.
In order to push down the update&insert logical to the HoodieRecordPayload for MergeInto, I make same change to the
HoodieWriteHandler and other related classes.
1、Add the inputSchema for parser the incoming record. This is because the inputSchema for MergeInto is different from writeSchema as there are some transforms in the update& insert expression.
2、Add WRITE_SCHEMA to HoodieWriteConfig to pass the write schema for merge into.
3、Pass properties to HoodieRecordPayload#getInsertValue to pass the insert expression and table schema.
