nats: cannot connect to ipv6 host

[jbergstroem]

Hello, after the auth fixes in 0.21.1 I'm attempting to connect to a ipv6 host, but vector doesn't seem to like my config. Something like:

[sources.my_nats]
  type = "nats"
  url = "nats://[::1]:4222"
  connection_name = "logs"

Gives:

2022-04-22T18:56:08.769003Z  INFO vector::app: Log level is enabled. level="vector=info,codec=info,vrl=info,file_source=info,tower_limit=trace,rdkafka=info,buffers=info,kube=info"
2022-04-22T18:56:08.769115Z  INFO vector::app: Loading configs. paths=["/etc/vector/vector.toml"]
2022-04-22T18:54:44.030456Z ERROR vector::topology: Configuration error. error=Source "my_nats": NATS Connect Error: failed to lookup address information: Name does not resolve

I've tried variations of the host but are running out of options. Any input much appreciated!

Hmm, I would think that that should work fine. I do see nats-io/nats.rs#322 but that should be fixed in the version of nats we are using. I'll try to verify and reply on that upstream issue if needed.
