- massive change to src/tgest/test_options.c since the sched options
  were added all over the place in it
- removing the sched options caused some tests to pass/fail in new ways
  so I assumed current behavior is correct and made them pass again
   - ex: "ConnLimit must be greater" lines
   - ex: "Authoritative directory servers must" line
- remove test_options_validate__scheduler in prep for new sched tests
