Description

Support SRV queries (used by Consul DNS, etc.) so that DNS can return IP/port combinations.

SRV is not supported by getaddrinfo_a so need to integrate with DNS library to make the query directly.

Contributor guide

Research direction
Examine the existing DNS resolver implementation in Envoy, identify where SRV record parsing can be integrated, and review how getaddrinfo a is used. Consider using a DNS library like c ares or similar to perform the SRV query directly.
