Reassign Issue Based on Updated Issue Owners Rule

### Problem Statement steps to reproduce problem 1. assign issue via issue owners rule 2. update the issue owners rule 3. send the issue.event to sentry again and expected it to get re-assigned 4. it doesn't get re-assigned using the new rule. (maybe sentry Server saw that it's already assigned, so it doesn't bother to check what rule should get assigned ### Solution Brainstorm Easiest for customer would be for Sentry backend to keep checking for an Issue Owner rule even if the issue is already assigned. Maybe it's not a check but just an assignment getting applied every time, and so it wouldn't be efficient for Sentry Server, if it turns out that it's super rare issue owner rules are getting updated a lot like this. Or, is there a feature like "Re-assign all Issues according to current state of Issue Owners" maybe a button from Project Settings, anything like that. ### Product Area Issues
