Define auto_activation_handler that activates VGs/LVs automatically based on the activation/auto_activation_volume_list (activating all volumes by default if the list is not defined). The autoactivation is done within the pvscan call in 69-dm-lvmetad.rules that watches for udev events (device appearance/removal). For now, this works for non-clustered and complete VGs only.
