Review Comment:
I'm confused why we don't need to update quota usage when the service
restarts. What happens when the scheduler goes down? Unless we always assume
that another host will perfectly transfer its workload to another host, there
can always be some scenario where the dagstatestore doesn't reflect the quotas
right?

Review Comment:
For context, we use runningDagIds to guard against multi increments and
decrements that can happen in startup/shutdown situations. It also guards
against scenarios where adhoc/runImmediately flows need to validate the quota
in the scheduler and not the DagManager
