> The role history won't reload historical placement data if the no. of roles
> doesn't match what it saved. It only persists numeric values and can't
> rebuild the information.
> This means if you add a new role to a cluster: no recovery of any previous
> placement
> It could persist the names -> priorities of each role, and reload the
> positions of those roles about which there are currently records, ignoring
> the rest.
