Add --max-workers and heuristics for parallel operations
add a global flag for --max-workers so users can limit the number
of parallel operations for a given function. also, when not limited
by max-workers, we implement a heuristic function that returns the
number of preferred parallel workers based on the number of CPUs and
the given operation.
