TaskService设置Task附加信息

任务附件(Attachment)创建与查询
任务评价(Comment)创建与查询

序号	方法	含义	描述
1	taskService.createAttachment("类型","任务id","流程Id","附件名称","附件描述","流或者url)	上传附件	省略
2	taskService.getTaskAttachments("任务id")	上传附件	省略
3	taskService.addComment("任务id","流程id","批注1")	添加审批批注	省略
4	taskService.getTaskComments("任务id")	查询审批批注	省略
5	taskService.getTaskEvents("任务id")	查询任务日志记录	省略
