Title: Update metadata server URL to be a FQDN.

Without a fully qualified domain name, containers (like Docker) can't
connect to the metadata server. Update the address for the metadata
server to be a FQDN so containers can use the library. See golang/oauth2#44.

I've tested this inside of Docker on CoreOS running on GCE, and can verify that
I have access to service accounts there.
