Enforce SLOs in Controller (?)
take the SLO as an argument, in controller (with a defult value of 50ms(?)), consider the demanded SLO in scheduling (obviously), after received the result back from the worker check if we responded before the request deadline or not.
or maybe if we don't want to be too strict on SLOs, in case we receive the result from the worker but the deadline for that request is passed, we send the result back to the client anyways.
so the requests eventually will have one of these states: in_time, late, dropped, failed
