> The block managers need an API that lets users choose where blocks are 
> placed. Different block managers support different levels of granularity 
> (e.g. locality in the log block manager can refer to disks or containers), 
> and so we need to find a way to abstractly describe this stuff.
> Some sample hints:
> # As close as possible to block X
> # As close as possible to <some opaque string>
> # On disk A
> # On disk A, B, or C
> # On any disk
> # Some combination of 1-2 and 3-5 (i.e. block locality + disk locality)
