This change wraps the std::process:Child that we spawn for WAL redo into a type that ensures that we try to SIGKILL + waitpid() on it. If there is no explicit call to kill_and_wait(), the Drop implementation will spawns a task that does it in the BACKGROUND_RUNTIME. That's an ugly hack but I think it's better than doing kill+wait synchronously from Drop, since I think the general assumption in the Rust ecosystem is that Drop doesn't block. Especially since the drop sites can be _any_ place that drops the last Arc<PostgresRedoManager>, e.g., compaction or GC. The benefit of having the new type over just adding a Drop impl to PostgresRedoProcess is that we can construct it earlier than the full PostgresRedoProcess in PostgresRedoProcess::launch(). That allows us to correctly kill+wait the child if there is an error in PostgresRedoProcess::launch() after spawning it. I also took a stab at a regression test. I manually verified that it fails before the fix to walredo.rs. fixes https://github.com/neondatabase/neon/issues/2761 closes https://github.com/neondatabase/neon/pull/2776
