bugfix. use public-hostname not public-ipv4

Amazon does not let you retrieve a public IP address or hostname of a newly created instance by querying http://instance-data/latest/meta-data/public-ipv4 but http://instance-data/latest/meta-data/public-hostname does work. The script was failing from not being able to retreive the public ip address and use it to configure the tunnel
