Summary: Add a config option to restrict the number of tree prefetches that can run in parallel. Without this applications that recursively walk a checkout tree can end up spawning a huge number of asynchronous prefetch operations. These prefetch operations are quite expensive today, as we currently have to fetch the full file contents in order to retrieve the file sizes. A recursive directory walk can end up building up a huge backlog of in-progress tree prefetches. This will slow down the directory walk, and it can take tens of minutes to finish processing the prefetch backlog even after the directory walk is aborted.
