SPIRE Server does not support binding to hostname

[mchurichi]

SPIRE Server help says it supports binding to a DNS name, but it fails when passing in localhost, is this right?

$ bin/spire-server run -h                    
Usage of run:
  -bindAddress string
        IP address or DNS name of the SPIRE server

$ bin/spire-server run -bindAddress localhost
could not parse bind_address "localhost"

Looks like an oversight. Code calls net.ParseIP, when it should probably combine the BindAddress and BindPort and pass it to net.ResolveTCPAddr
