On startup, the catalog manager often emits this warning:
W0104 16:34:39.405272 2555 catalog_manager.cc:365] Catalog manager background task thread going to sleep: Service unavailable: Catalog manager is not initialized. State: 1
This is because we wait to flip the catalog manager state to 'running' until after starting the background task thread. We could either change where the state change happens, or we could just ignore 'ServiceUnavailable' status instead of warning it.
