How will this behave during the creation of a very large table, or at the start 
of a rereplication storm? That is, how will it behave when we have to create 
many tablets all at once? Won't it bias all of those tablets' data dir groups 
towards the emptier data dirs? At least with the status quo, each created 
tablet affected the power-of-2 choice of the next created tablet (by increasing 
the number of tablets in the chosen data dirs); here the available disk space 
won't change until the tablets actually start filling up.
