Revert "fixing memory leak"

This reverts commit 25ddf1cb350f2ad5932c604ec7399af0e7b90d80.
adding default HLT configs
fixing memory leak
Add ability to pass `das_client.py` options via `runTheMatrix.py`.

Similar to `--commands`, it is now possible to specify extra
das_client.py options via `--das-options`.

Usage of this includes, but is not limited to:

- Supporting cached queries, see also dmwm/DAS#4142.
- Running against a test bed instance.
Refactor InputInfo to easily get the list of DAS queries.

This slightly refactors the API of InputInfo to allow easier access to
the actual DAS query(s) given a workflow.
Add option to dump job reports.
