switchover v5
Switches over to new write leader.
Synopsis
Switches over to new write leader. Use switchover method 'fast' for immediate switchover. Use 'strict' to wait until lag is less than 'route_writer_max_lag' on the given target node. If switchover fails due to timeout or any other issue, BDR might elect a write leader that's different from the given target node.
