1. Proposed title of this feature request
Enable configuration of hosts plugin in CoreDNS
2. What is the nature and description of the request?
In ARO we currently use dnsmasq to serve the api and api-int records as well as a list of "gateway domains" to the cluster. The gateway domains are public records but we need to serve alternate A records for them to redirect the traffic over a private link to a proxy. ARO wishes to stop using dnsmasq for this, so to preserve this functionality we need CoreDNS configured with a hosts plugin block similar to
.:5353 {
...
hosts {
10.0.0.4 api.m71z3hze.eastus.aroapp.io api-int.m71z3hze.eastus.aroapp.io

3. Why does the customer need this? (List the business requirements here)
ARO needs this to remove our dependence on dnsmasq and move closer to vanilla OCP. ARO also needs this to remove the fork of the installer which is patched to add the dnsmasq functionality.
