Sean Mooney 6bb6c0bbdd Harden placement init under wsgi ...

- 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 of
  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.
