Description

Fixes tests:

• TestDNS_Lookup_TaggedIPAddresses (passing). part of NET-7644.
• TestDNS_ServiceLookup_WanTranslation (not passing). part of NET-7634.

Notes

• this logic requires addtional data from the database in the TaggedAddresses collection on nodes and services, as well as it also requires whether you are asking for IPV6, IPV4 or ANY,
• since it requires data from the database, there needs to be a change to DiscoveryResult.
  • Right now it is just TaggedAddresses on the Discovery Result level.
  • Also, the Tagged Address on the service has address and PortNumber, so I hacked around with moving PortName and PortNumber to the Location struct and then making Tagged Addresses a map[string]*Location on the discovery result.
  • This is still a WIP and it looks like both Node and Service will need tagged addresses, so we will consider moving TaggedAddresses into DiscoveryResult.Node and DiscoveryResult.Service.
• On the translation end of things, rather than copying all of the address translation code, I opted to ust inject the function from the agent as we did with various rpc functions.
  • Since the return type is in the agent package, I had to move the TranslateAccept enum in internal/dnsutil/dns.go to avoid import cycles.
