> A node restart currently iterates through each core and publishes an item to the Overseer
queue to mark that core as 'down'. This is inefficient if each node has many cores and causes
overseer to be overwhelmed with requests. We can publish a single 'down' status for the entire
node and have the overseer do the rest.
