This commit updates the DNS query locality parsing so that the virtual
IP for an imported service can be queried.
Note that:
- Support for parsing a peer in other service discovery queries was not
added.
- Querying another datacenter for a virtual IP is not supported. This
was technically allowed in 1.11 but is being rolled back for 1.13
because it is not a use-case we intended to support. Virtual IPs in
different datacenters are going to collide because they are allocated
sequentially.
Previously, we were only returning a single ListenerPort for a single
service. However, we actually allow a single service to be serviced over
multiple ports, as well as allow users to define what hostnames they
expect their services to be contacted over. When no hosts are defined,
we return the default ingress domain for any configured DNS domain.
To show this in the UI, we modify the gateway-services-nodes API to
return a GatewayConfig.Addresses field, which is a list of addresses
over which the specific service can be contacted.
