> On region split, the daughter regions are deployed on the same host as served the split
parent.  This makes it so currently (unless the cluster is restarted), as a table grows, all
its regions remain on the one server.
> Instead, jurisdiction over who serves daughter splits should be passed to the master.
 If possible, before making a determination, the master should take into consideration current
cluster loadings and region distribution.
