Allow same-net, same-priority zone filling 

When two zones with the same net and same priority overlap, they should
both be filled, matching the behavior of v6.  If you would like an
explicit override of one or the other, you need to set the zone priority
higher.  Relying on the UUID as a tie breaker is good for zones with
different nets but creates unexpected changes from v6 when applying it
to zones of the same net
