Clean up debug module options. (#299)

* Clean up debug module options.

1. Instead of passing each one a few levels deep, create
debug_module_config_t which contains them all.
2. Rename all those command line options so they start with --dm for
debug module.
3. Add --dm-no-halt-groups to disable halt group support.

* Update changelog.
