[Feature ]Linkis metadata information storage supports multiple databases

[binbinCheng]

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
