BREAKING feat(nslord,nsmaster): upgrade to pdns 4.3

This comes with a mandatory database migration on dblord and dbmaster,
https://github.com/PowerDNS/pdns/blob/rel/auth-4.3.x/modules/gmysqlbackend/4.2.0_to_4.3.0_schema.mysql.sql

The commit also contains two small fixes in the database schema that
are not mandatory to apply.
