> Fix some minor bugs in the user documentation and exception messages:
> - When the layout version is mismatched, mention the new "-rollingUpgrade started" option in the exception message.
> - For the non-HA in the user doc, "start NN as standby" is incorrect -- there is no standby in non-HA case.
