Refactoring workload list parsing to Python (#1089)

* Refactoring workload list parsing to Python

* Fix goldens to use [0] instead of [*] in refactoring branch

* Remove _sum_counts from refactoring branch

* Update goldens

* Update goldens with PYTHONPATH=src

* Remove test-queued-job and move super_slicing test to wildcard

* Address refactoring feedback: fix row delimiter, restore headers, use case-insensitive matching

* Address refactoring feedback: add ROW_DELIMITER const, render <empty> row when empty

* Rename delimiter and fix cluster delete workloads parsing

* Migrate to JSON parsing and use _WorkloadListRow dataclass
