Fix documentation around get*DomainMetadata

* `GetDomainMetadata` and `GetAllDomainMetadata` state `false` can be returned, but doing this results in an error.
* Somewhere between PowerDNS 4.2 and 4.4, `GetAllDomainMetadata` became mandatory: a backend returning 404 will result in PowerDNS responding with `SERVFAIL`.
