Should we add third-party onboarding examples to the README?

[chicks-net]

In #4205 I learned about SukkaW/dnscontrol-gitops-template. Previously I built fini-net/fini-coredns-example. Both of these are attempts to make it easier to onboard folks onto dnscontrol.

• Should we link to these "external to the core projects" efforts in the README? I'm guessing we'd want some sort of disclaimer that support is provided by the originator and not the main project.
• Should we note that things like coredns are supported because they are BIND compatible? Other major examples are NSD (Name Server Daemon), Knot DNS, and PowerDNS Authoritative.
