After a local certification failure, commit order is released without the setting the current position in DBMS. Which results in diverging positions between provider and DBMS, if clean shutdown happens right after local certification failure. This patch add method set_position() to server_service class. So that wsrep-lib can instruct DBMS to set the current position after local certification failure releases commit order.
