If an allocation is slow to stop because of `kill_timeout` or `shutdown_delay`, the node drain is marked as complete prematurely, even though drain monitoring will continue to report allocation migrations. This impacts the UI or API clients that monitor node draining to shut down nodes. This changeset updates the behavior to wait until the client status of all drained allocs are terminal before marking the node as done draining.
