Description

Now, a user just can see subtask current attempt in the timeline. If job failover, can not see some has canceled task timeline.

Proposed Changes

• In the 'subtasks' array, we have objects of type SubtaskTimeInfo with only one added field 'attempt'.
• add query parameter show-history, the default value is false. If show-history is true, information for all attempts including
  previous ones will be returned
• URL: /jobs/:jobid/vertices/:vertexid/subtasktimes?show-history=true
• response：
