Datax 支持内嵌式调用和数据进度api获取和控制api

目前看Datax 都是通过shell 脚本传递json 文件方式直接调用，是进程级别的，是否支持有相关api 在应用内，特别是spring 应用内进行调用，进行任务的调用和控制

Start by reviewing DataX's existing shell-script and JSON-file process invocation described in the issue. Investigate what an in-application API for Spring applications would need for task invocation, progress retrieval, and task control. Done would require a defined embedded API and behavior for these operations, but the issue does not name files, tests, or acceptance criteria.
