[tor-relays] Tor exit relay lifecycle - update

Hello! We have been working on a proposal to introduce an exit relay lifecycle (similar to the one we have for non-exit relays)[1]. That proposal got recently accepted and merged[2] and now we need to get it implemented. Folks interested can follow the implementation part by tracking the respective ticket in core/tor[3]. For more context see the discussion in the original exit lifecycle ticket[4] as well. Thanks, Georg [1] https://gitlab.torproject.org/tpo/community/policies/-/issues/32 [2] https://gitlab.torproject.org/tpo/community/policies/-/blob/main/docs/relays...
