[FEA] Generate a report of tasks on the core output

[amahussein]

Is your feature request related to a problem? Please describe.

The core tools generate reports about jobs/stages/sqls and failed entries including Tasks.
However, there is no report of the details of tasks. This sounds odd that we generated failed tasks but nothing about details of the tasks themselves.
This might be helpful to:

• debug/verify the aggregations on higher level.
• troubleshooting status and durations of different tasks
• the consumer of the output has the ability to build their own logic to calculate the wall-clock-durations/sql-durations per app.

Describe the solution you'd like

• no need to add the report to the text format. Tasks are huge number and we do not want that overhead.
• Generate a new report csv file that
