Review Comment:
I think runImmediately is a fairly common user use-case. We had a large
scale user who would store flows with a schedule very far out, and then invoke
it in an adhoc way using runImmediately. This would help them run backfills
with the same configurations if needed, and also avoid concurrency issues as
scheduled flows validate that they're not already running (but adhoc does not
do this).

> 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.
