Review Comment:
Yeah, when we disable run immediate, we should be able to support adhoc run
for scheduled flow once we move adhoc flow to be triggered by dag action store
instead of spec store. But now we might want to keep the same behavior as
before.
Specifically for the use case where the schedule is far out and they want to
run it immediately, I believe we want to reject the request and ask them to
submit that again when quota is good

> Now, when add/update flow spec, we rely on scheduler to compile the flow and
> return status, but in warm standby mode, where every host can accept and
> process request but not running the flow, we should be able to compile flow
> without scheduler.
