2. Remove scheduler waits to speed up recovery time (knative#8200) …

   Currently, the scheduler and autoscaler are single threads and use
   a lock to prevent multiple scheduling and autoscaling decision
   from happening in parallel; this is not a problem for our use
   cases, however, the multiple `wait` currently present are slowing
   down recovery time.
   
   From my testing, if I delete and recreate the Kafka control plane
   and data plane, without this patch it takes 1h to recover when there
   are 400 triggers or 20 minutes when there are 100 triggers; with the
   patch it is immediate (only a 2/3 minutes with 400 triggers).
   
   - Remove `wait`s from state builder and autoscaler
   - Add additional debug logs
   - Use logger provided through the context as opposed to gloabal loggers
     in each individual component to preserve `knative/pkg` resource aware
     log keys.
