Set server position after local certification failure

Browse Source 
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.
