Status: allow IPs and move properties to base class

We only allowed servers with the dns-name format, as such status
server may often be in internal networks and with no hostname
(testing, small network so no dns, ...) do not limit the
configuration possibilities with no reason.

Also move the base property part to the base Status class, all
current plugins use server and port so no need for double
declaration of format/descriptions.

If a future plugin doesn't need them it can omit them by not
returning the respective properties in the options method
inherited by SectionConfig.
