> To setup a SBN we currently format the primary then manually copy the name dirs to the
SBN. The SBN should do this automatically. Specifically, on NN startup, if HA with a shared
edits dir is configured and populated, if the SBN has empty name dirs it should downloads
the image and log from the primary (as an optimization it could copy the logs from the shared
dir). If the other NN is still in standby then it should fail to start as it does currently.
