- This change tries to address an edge case discovered when running placement under mod_wsgi where if the placement wsgi application is re-initialize the db_api configure method attempts to reconfigure a started transaction factory. - This since oslo.db transaction factories do not support reconfiguration at runtime this result in an exception being raised preventing reloading of the Placement API without restarting apache to force mod_wsgi to recreate the python interpreter. - This change introduces a run once decorator to allow annotating functions that should only be executed once for the lifetime fo an interpreter. - This change applies the run_once decorator to the db_api configure method, to suppress the attempt to reconfigure the current TransactionFactory on application reload.
