leesf 5ce45c440b [HUDI-3172] Refactor hudi existing modules to make more code reuse in V2 Implementation (#4514)
* 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.

# Description of the relationship between each module
This repo contains the code that integrate Hudi with Spark. The repo is split into the following modules
`hudi-spark`
`hudi-spark2`
`hudi-spark3`
`hudi-spark3.1.x`
`hudi-spark2-common`
`hudi-spark3-common`
`hudi-spark-common`
* hudi-spark is the module that contains the code that both spark2 & spark3 version would share, also contains the antlr4
file that supports spark sql on spark 2.x version.
* hudi-spark2 is the module that contains the code that compatible with spark 2.x versions.
* hudi-spark3 is the module that contains the code that compatible with spark 3.2.0(and above) versions。
* hudi-spark3.1.x is the module that contains the code that compatible with spark3.1.x and spark3.0.x version.
* hudi-spark2-common is the module that contains the code that would be reused between spark2.x versions, right now the module
has no class since hudi only supports spark 2.4.4 version, and it acts as the placeholder when packaging hudi-spark-bundle module.
* hudi-spark3-common is the module that contains the code that would be reused between spark3.x versions.
* hudi-spark-common is the module that contains the code that would be reused between spark2.x and spark3.x versions.
