[Feature ]Linkis metadata information storage supports multiple databases

**描述**：Linkis的元数据信息存储支持多数据库

**需求**：将mybatis的mapper文件移动到resources/mapper/mysql/）下，在支持其它数据库时，可以新建一个子目录，如：resources/mapper/postgresql/

------

以jobhistory 为例 linkis-public-enhancements/linkis-jobhistory,当前linkis自身数据，只支持mysql 数据库方式。有些用户可能不是mysql，如果希望同时支持其他数据库如 PostgreSQL，这样用户可以根据自己实际使用情况选择使用

```
|-- main
| |-- java
| |-- resources
| | `-- mapper
| | `-- common
| | |-- JobDetailMapper.xml
| | `-- JobHistoryMapper.xml

```
需要适配
可以考虑 通过不同文件名区分 如

```
|-- main
| |-- java
| |-- resources
| | `-- mapper
| | `-- common
| | |-- JobDetailMapper.xml
| | `-- JobHistoryMapper.xml

|-- main
| |-- java
| |-- resources
| | |-- mysql
| | | `-- mapper
| | | `-- common
| | | |-- JobDetailMapper.xml
| | | `-- JobHistoryMapper.xml
| | `-- postgresql
| | `-- mapper
| | `-- common
| | |-- JobDetailMapper.xml
| | `-- JobHistoryMapper.xml

```
