Version

After enabling JWT auth on our cluster, all of our Go functions started failing. This is because authentication information is only passed to the pulsar-admin command, and also because the Go function SDK has no concept of auth providers.

Minimal reproduce step

Just enable auth, and watch your go functions start to complain:

broker.pulsar.svc.cluster.local:6650 local_addr=172.27.168.187:37436
