Try all available addresses when connecting to localhost (127.0.0.1 and ::1)

See original GitHub issue

In node v17 (specifically https://github.com/nodejs/node/pull/39987), we switched the default ordering of dns entries to follow what the OS is providing us vs reordering to put IPv4 addresses always first. This creates quite a few issues for folks as some tools only listen to 127.0.0.1 and not ::1.

I think we should try multiple addresses when dealing with localhost when establishing a new connection.

Should we enable it by default? Agents should be able to set this option already, under connect in options.

Yes, we’d need to enable that setting once it lands.
