Curl statements to include globoff for IPv6 URLs

Novaclient displays curl statements for debugging/troubleshooting
purposes. For IPv6 URLs, curl requires --globoff to be passed in
the arguments. Since novaclient does not use curl directly, this
patch displays the curl commands with globoff option which works
for both IPv4 and IPv6 URLs.
