> BootstrapStandby should not require a rollEdits on active node

>
> Currently, BootstrapStandby uses a rollEdits() call on the active NN in order
> to determine the most recent checkpoint and transaction ID. However, this
> means that you cannot bootstrap a standby when the active NN is in safe mode
> -- i.e you have to start the whole cluster before you can bootstrap a new
> standby. This makes the workflow to convert an existing cluster to HA more
> complicated. We should allow BootstrapStandby to work even when the NN is in
> safe mode.
