Daniel F. Dickinson 1a77490969 dnsapi: Add option to set zone for nsupdate
Some DNS servers for which dns_nsupdate.sh is applicable (such
as dyn.com's 'Standard DNS' TSIG update mechanism), require that
the zone be set during the nsupdate transaction.  Therefore we
add a new environment variable NSUPDATE_ZONE which is used to
set the zone for the DNS TSIG transaction.
