In the midst of working on #770, I realized all local dbt data diffs run sequentially. This makes data-diff run slower than necessary to reach the same results. Race conditions shouldn't be an issue because each query
data-diffruns are independent by design. This is also validated by the fact that cloud data diffs have concurrent diffs already built for awhile and have not encountered bugs.ThreadPoolExecutorfor cloud diffs and local diffsBefore this PR: Sequential performance is slow
After this PR: Consistently get 2-4x performance increase with concurrency enabled
