Initial sd_notify support was added in #3963, but that sent signals from both cmdRun and cmdReload. This approach has two drawbacks: - Reloads initiated via the API do not send signals. - The signals are sent from different processes, which requires the `NotifyAccess=exec` directive in the unit file. This change moves the NotifyReloading and NotifyReadiness invocations to Load, which address both of those drawbacks. It also adds a complimentary NotifyStopping method which is invoked from handleStop. All the notify methods are defined in a notify package to avoid an import loop.
