Testing new urls accepted
gsutil is run on all supported gs urls

When the url contains "storage.googleapis.com" it is treated as
a google storage url and runs gsutil on it. This is eager and may
check urls that are not valid. In this case gsutil will fail and
the default correct behavior will occur.
  Enabled extglob so gsutil is run

Google Storage URLs are supported on startup.

The script should allow for the following gs urls:

http://storage.googleapis.com/bucket/object/
http://bucket.storage.googleapis.com/object/
http://commondatastorage.googleapis.com/bucket/object/
https://storage.googleapis.com/bucket/object/
https://bucket.storage.googleapis.com/object/
https://commondatastorage.googleapis.com/bucket/object/

commondata URLs are depricated but currently supported.

Add client timeout to metadata hanging request

This ensures we don't hang even if the metadata server
does not honor the timeout we pass it. We don't need
to handle the exception as the daemon loop catches and
retries on all exceptions.
Adjust timeout on hanging metadata request

* Tell urllib2 to wait a little longer than the timeout
  we gave to metadata server.
* Reduce timeout from 5mins to 1min.
