Lina JodoinandGitHub 19fc1ad532 Hook up CHASM Scheduler to Frontend handler (#8694) ...

## What changed?
- Frontend workflow_handler can now route to CHASM scheduler, depending
on experiment flag/dynamic config
- Scheduler functional test has been updated to exercise both V1 and V2
scheduler
- Small fixes throughout scheduler codebase to address differences
noticed during functional testing
- Nexus callback mechanisms updated to allow the CHASM internal callback
URL

I plan to address the TODO around LastCompletionResult's assertion in a
separate follow-up PR.

## How did you test it?
- [ ] built
- [ ] run locally and tested manually
- [ ] covered by existing tests
- [ ] added new unit test(s)
- [x] added new functional test(s)

## Potential risks
- Existing V1 tests are preserved, to show that the V1 codepath still
works as-is. All new CHASM handling logic falls back to V1 in absence of
a positive response. CHASM can only be opted in for a schedule during
creation, controlled by dynamic config/experimental header.
