Review Comment:
Using `subTaskState` as the path param doesn't look natural to me. I took a
look at other APIs and the pattern is to have `taskType or taskName` path
parameter.
Please give 5-10 min to see if there's a better way to represent this. If
feasible, I personally would still prefer to have a single API with all
different filters as query params.. (e.g. `GET /tasks/subtask/progress` <- this
can reuse the existing minion side API)

Review Comment:
`Minion work IDs` -> `Minion worker IDs`

Review Comment:
I think that we can merge this function with `/tasks/subtask/progress`?

Review Comment:
I guess that `StringUtils.split()` would handle the trimming?

Review Comment:
What if we return the task names and corresponding subtasks from
`/tasks/subtask/state/{subTaskState}/progress` and asks ppl to use
`/tasks/subtask/{taskName}/progress` to fetch for each progress of the subtask?
The existing API allows us to provide the list of subtasks so we can fetch the
information with a single call if needed.
