[tools] Let pdnsutil always setup a SOA-EDIT-API metadata when creating zones

[miodvallat]

Short description

This is a fix for #9096. Every time pdnsutil will create a zone, it will now put a SOA-EDIT-API metadata with a value of DEFAULT, to match what creating the zone from the API would have done.

Ok, I lied, not every time. When migrating using pdnsutil b2b-migrate, this will not be done, as this operation will copy all the existing metadata from the source (which may, on purpose, not have a SOA-EDIT-API metadata).
