Patch update.
+ Address review comments including unittest for
HardAffinityFragmentParallelizer
+ Fix Limit0 issue when one of the GroupScans in limit0 query has hard
assignment requirements (in which case we can't run the entire query in one
fragment). @sudheeshkatkam Can you review this change for any perf
implications? I tested limit0 queries on parquet table containing more than 1k
files. I didn't see any regressions.
