Burn Lewis resolved UIMA-5086.
    Resolution: Fixed

After rounding up a reserve request consider machines up to 
ducc.rm.reserve_overage GB larger than this. Search machines in this range, 
taking the smallest empty one or the one with the least investment and no fixed 
work. The GB overage is rounded down to a multiple of the quantum.  Once a 
resource has been identified the request is upgraded to match the size of that 
resource, and on subsequent scheduling phases only resources of that size are 
considered.  Hovering over the Memory field on ducc-mon's Reservations page 
will show the size of the original request.
