The origin show analyze code would traverse the task id to task map for each job to get all the tasks for this job, which is very slow.
This pr keep the task ids for each job in the job info class, so that we can get the tasks by task ids directly.
To show 1100+ jobs with 11000+ tasks, the time costing is reduced from 0.14s to 0.01s.
