新增功能-api生成数据库并初始化回写配置

修改gva initdb 判断是否已经创建的一些小问题
新增api生成数据库并初始化回写配置
修改文件：
server/cmd/gva/initdb.go
server/cmd/information/data_authorities.go
server/cmd/information/workflow.go
server/initialize/gorm
server/main.go

新增文件：
server/api/v1/sys.initdb.go
server/middleware/init.go
server/model/sys_init.go
server/service/sys_initdb.go
servcer/utils/init_db.go

迁移文件
server/cmd/gva/mysql.go->server/utils/mysql.go
