[MAAS 3.4- RFE/Documentation] Domain DNS Delegation

Hello,

When delegating MAAS to domains its not entirely clear as per the MAAS docs or forum how to correctly configure MAAS to perform DNS delegation.

The process to configure MAAS is not clear and leads to many false negatives and false positives, this issue is to request some documentation on configuring MAAS with the correct configuration, between two MAAS' installations.

This may help with issues such as: https://discourse.maas.io/t/issues-integrating-maas-dns-into-a-large-corporate-environment/4304 where end-users are unable to know if MAAS is configured correctly and incorporate MAAS into their environments.

When configuring DNS delegation using information available I am unable to configure delegation by creating NS records, although I can make the solution work briefly if I run sudo snap restart maas on the top-level DNS (MAAS) server.

This issue is to request this process be clarified and any issues within maas which prevent domain delegation are investigated.

Thanks,
Peter
