Change-Id: I2b2fb4c746fa26097110f08d211c28076fd81942

Adding first pass of dragonfly custom model: routings (adaptive, progressive adaptive, minimal, non-minimal) should be functional with DF traces, need to update for making optimistic mode functional

Change-Id: I5257228912bbf3d8e1228ead4d2a0910f1e2da6b

Adding updated allocation generator script (uses random number seeds for multiple allocation files), torus cleanups

distcheck still doesn't succeed - there are a bunch of test files that don't
get cleaned up. moving on, but will make a ticket for it.

00001,00002,...,00010 rather than 1,2,...,10 for IDs (correct lexicographic
ordering)
