perf: 优化对 GSE任务查询结果为空的处理

[wangyu096]

问题

GSE 可能会出现任务延迟的情况，导致返回的结果为

[2023-06-13 19:24:50.776]  INFO [job-execute,9ecc92710f2cd5111024c310aabbc2f0,49ea0f2b7fa2d091] 32257 --- [task-result-handle-12533] c.t.bk.job.common.gse.v1.GseV1ApiClient  : GetScriptTaskDetailResponse: api_task_detail_result(bk_error_code:1000115,bk_error_msg:redis reply is not string,result:null)

Job 处理响应结果的时候，由于 result 为空，出现了空指针错误

java.lang.NullPointerException: null

优化方案

1. 对于 GSE 返回的 result 为空的场景，进行容错处理。只有到 result 持续为空一段时间之后，才会判定为任务失效，才会终止调度，并设置任务为状态异常
