Ian Littman f4f249a5eb Only use one nginx worker, add a slight wait post-nginx-reload, to properly upgrade-test schema changes that aren't backward-compatible on the "get enroll secret" code path (#26008) ... For #26003. Will add more context to that ticket. This is a robustness fix to the upgrade test, which pulls tags/branches from Docker, so this does _not_ need to be cherry-picked. To confirm this fix, run the upgrade test from <4.63.0 to >= 4.63.0 and see it pass rather than fail. # Checklist for submitter - [x] Added/updated automated tests - [x] A detailed QA plan exists on the associated ticket (if it isn't there, work with the product group's QA engineer to add it) - [x] Manual QA for all new/changed functionality		2025-02-03 19:55:26 -06:00
