----------------------------------------------------------
bq. Should that be graceful?
What will the UI do? Will it retry? Should it show everything as unavailable
even if 9 out of 10 tasks had data available?
bq. do we have a final idea on how filters and sorting must work?
Can be added in a follow-up jira. If the current plan is to get all task Ids
from ATS and then update them live via data from the AM, that should be fine
for an initial approach.

> Add AM API for fetching realtime tasks info:
> - API endpoint : /ws/v2/tez/tasksInfo
> - Query Params:
> -- dagMinID: dagMinID = dagIndex, (mandatory).
> -- vertexMinID: A comma separated list. vertexMinID = vertexIndex.
> -- taskMinID: A comma separated list. taskMinID = vertexIndex_taskIndex
> -- limit: Maximum number of items to be returned (Defaults to 100).
> - If taskMinID is passed: All (capped by limit) the specified tasks will be
> returned. vertexMinID if present wont be considered.
> - IF vertexMinID is passed: All (capped by limit) tasks under the vertices
> will be returned.
> - If just dagID is passed: All (capped by limit) tasks under the DAG will be
> returned.
> - Data returned: complete task id, progress, status
