Bug Description

These cases seem to produce race conditions in shutdown or conf change:

1) close_connections() is called before wsrep->disconnect() in shutdown (wsrep applier hangs)
2) wsrep_close_client_connections() is called from view handler in case of non-prim (rapid non-prim - prim transitions cause race between committing transactions and applier trying to close client connections)
