Subject: [PATCH] nut: Infer role from server name, set commands

Since the "primary" `upsmon` is always (for our purposes) running on the
same host as `upsd`, there's no reason to specify both values.

All systems need a shutdown command; one is not set by default.

The primary system is the only one that should send notifications.
