display: use range to represent partitions in a task (#194)
This change makes the explain output more concise by changing the stage formatting from ``` Tasks: t0:[p0,p1,p2,p3,p4,p5] t1:[p0,p1,p2,p3,p4,p5] t2:[p0,p1,p2,p3,p4,p5] t3:[p0,p1,p2,p3,p4,p5] ``` to ``` Tasks: t0:[p0..p5] t1:[p0..p5] t2:[p0..p5] t3:[p0..p5] ``` Closes: #192
