Previously, it was possible for the spool in tasks to end up being spawned on just a subset of the available spool in threads if there was some idleness in the task processing startup, for example, if the dns for the first few messages returned from spool enumeration is slow to resolve. In that situation we can end up with no effective concurrency during spool enumeration, leading to a very slow startup. What I'd like to see to resolve this wholistically is adopting the main tokio work stealing task runner, but we are prevented from doing this until mlua 0.10 is released. What this commit does is refactor the core of the Runtime code to extract the function that sets up the thread pool so that we can directly spawn the spool in thread logic into each of the worker threads, guaranteeing that they are spread out one to a thread. With this change in place, I always observe 100% utilization of spoolin on startup where I previously would see only around 60 or 70%.
