The changes based on https://github.com/apache/incubator-kyuubi/pull/1226#issuecomment-942979767
In this PR, I'm going to remove profiles `kyuubi-extension-spark-3-1` and `kyuubi-extension-spark-3-2`, and keep `spark-3.0`, `spark-3.1`, `spark-3.2`.
After changes, when `spark-3.1` is active, set `spark.version` to 3.1.2 and enable `kyuubi-extension-spark-common` module and `kyuubi-extension-spark-3-1` module, `spark-3.2` does the same thing

### What is the purpose of the pull request
pr for KYUUBI #939:Add Z-Order extensions to optimize table with zorder.Z-order is a technique that allows you to map multidimensional data to a single dimension. We did a performance test
for this test ,we used aliyun Databricks Delta test case
https://help.aliyun.com/document_detail/168137.html?spm=a2c4g.11186623.6.563.10d758ccclYtVb
Prepare data for the three scenarios:
1. 10 billion data and 2 hundred files（parquet files）: for big file(1G)
2. 10 billion data and 1 thousand files（parquet files）: for medium file(200m)
3. one billion data and 10 hundred files（parquet files）: for smaller file(200k)
test env：
spark-3.1.2
hadoop-2.7.2
kyubbi-1.4.0
test step：
Step1: create hive tables
```scala
spark.sql(s"drop database if exists $dbName cascade")
spark.sql(s"create database if not exists $dbName")
spark.sql(s"use $dbName")
spark.sql(s"create table $connRandomParquet (src_ip string, src_port int, dst_ip string, dst_port int) stored as parquet")
spark.sql(s"create table $connZorderOnlyIp (src_ip string, src_port int, dst_ip string, dst_port int) stored as parquet")
spark.sql(s"create table $connZorder (src_ip string, src_port int, dst_ip string, dst_port int) stored as parquet")
spark.sql(s"show tables").show(false)
```
Step2： prepare data for parquet table with three scenarios
we use the following code
```scala
def randomIPv4(r: Random) = Seq.fill(4)(r.nextInt(256)).mkString(".")
def randomPort(r: Random) = r.nextInt(65536)
def randomConnRecord(r: Random) = ConnRecord(
src_ip = randomIPv4(r), src_port = randomPort(r),
dst_ip = randomIPv4(r), dst_port = randomPort(r))
```
Step3： do optimize with z-order only ip， sort column： src_ip, dst_ip and shuffle partition just as file numbers .
execute 'OPTIMIZE conn_zorder_only_ip ZORDER BY src_ip, dst_ip;' by kyuubi.
Step4： do optimize with z-order only ip， sort column： src_ip, dst_ip and shuffle partition just as file numbers .
execute 'OPTIMIZE conn_zorder ZORDER BY src_ip, src_port, dst_ip, dst_port;' by kyuubi.
---------------------
# benchmark result
by querying the tables before and after optimization, we find that

- correct the config key; we should use `spark.` as the prefix
