probed in the repository
There's a scenario where an undesired conflict happens:
1. Register a service and custom host with addresses and public key.
2. Register another service using the same hostname and public key.
While the second registartion is being probed, its KEY RR is considered
as conflicting with the address record of the first registraiton. This
shouldn't be a reasonable behavior because the address record itself is
from the repository itself.
