allow per type record counts to be specified in update-policy
Allow per type limits to be specified as part of a update policy. This will allow ISP's to specify practical limits.
e.g. Clients could be allowed to add a single PTR record for their machine.
zone "in-addr.arpa" {
type master;
file "x";
update-policy {
grant * tcp-self . ptr(1);
};
};closes #1657 (closed)
