Write function. 2.1 Mapping tree model to table model; Retain the logic of tree model as much as possible. In root.test.g_0.d_0, test is the database, g_0_table is the table name, and d_0 is the identifier column; that is, all the data of an organization is stored in one table, and only one database is created; 2.2 Create database and table; The database creation uses synchronization blocks to ensure that only one database is created; 2.3 Write request requires new information columnCategories Add the attribute columnCategories in sensor. If it is a table model, create a table containing columnCategories in gentable. 2.4 Generate an identifier column The name of the identifier column is currently fixed as "device_ID". In initworkload, if columnCategories == ID, the value of device_ID is generated.
新增 boolean 参数 ENABLE_TABLE，默认为 false。在 dbConfig 中增加 SQL_dialect ，用于为 session 指定 sql 解析。在加载配置阶段根据 ENABLE_TABLE 的值为 SQL_dialect 赋值。
原本“支持表模型”与“新增四种数据类型”应该基于同一 master 修改，由于表模型支持 String 等数据类型，因此本次在上一次 PR 上修改。如若为大家造成困扰，我可以 cherry-pick 哈。

目前在 initSensorCode 与 initWorkload 创建存储标识列的sensor太死板了。大家有没嘚好的 idea
