If you have a rule say with 10+ jql conditions (or other validators that need to talk to Jira), then this can take longer than 30 secs to process. API has a 30 second request limit.
We should make a few changes here:
Set Router timeout after 30 secs since there's no point in processing longer requests (would flag more problems and save some $$)
Remove slow validators. There's not much we can do here. The audit log would show the error anyways and we have client-side validation already for things like JQL
Check all validators.
Fix client-side code to handle timeouts and display an error!
