When running a lot of tests simultaneously, the time delta was too small.

Both are thread-per-host schedulers. The Rust scheduler is designed to behave very similarly to the C scheduler (each thread waits on its own semaphore, runs the task, then updates a count down latch).

This replaces shadow's C thread-per-host scheduler with a Rust thread-per-host scheduler. The Rust scheduler is designed to behave very similarly to the C scheduler (each thread waits on its own semaphore, runs the task, then updates a count down latch). It uses the existing C affinity code to assign logical processors to OS cores.
