Automated DNS

[dronenb]

I want to use BIND in OPNSense for automated DNS so that ownership can be tracked via TXT records, that way when I rebuild the cluster it can re-take ownership of records the previous cluster had created.

• dns/bind: Add option to allow the rndc-key for zone transfers opnsense/plugins#4177
• os-bind: Improve RNDC Key functionality and fix out of sync journals opnsense/plugins#4352
