[tor-relays] Reapply exit policy on reload

Hi to all dear exit operators, If you are interested in applying the exit policy on reload and not by restarting tor please note: https://gitlab.torproject.org/tpo/core/tor/-/merge_requests/735#note_3051797 Quote David: "Can you give us a sense of how many exit operators use this? If there is a large enough need for this, we can evaluate this for next release but it needs to be for more than 1 operator for such feature."
