* Add logging on shutdown * Replace tokio::spawn with handle.spawn * Upgrade tokio * Add a task executor * Beacon chain tasks use task executor * Validator client tasks use task executor * Rename runtime_handle to executor * Add duration histograms; minor fixes * Cleanup * Fix logs * Fix tests * Remove random file * Get enr dependency instead of libp2p * Address some review comments * Libp2p takes a TaskExecutor * Ugly fix libp2p tests * Move TaskExecutor to own file * Upgrade Dockerfile rust version * Minor fixes * Revert "Ugly fix libp2p tests" This reverts commit 58d4bb690f52de28d893943b7504d2d0c6621429. * Pretty fix libp2p tests * Add spawn_without_exit; change Counter to Gauge * Tidy * Move log from RuntimeContext to TaskExecutor * Fix errors * Replace histogram with int_gauge for async tasks * Fix todo * Fix memory leak in test by exiting all spawned tasks at the end
