[Bug 980940] [NEW] euca2ools does not respect the --region option correctly

[Andrew Glen-Young]

Public bug reported:

The euc2ools commands do not support the --region flag for anything
other than EC2. I would like to define multiple regions and use these
commands against Eucalyptus and Openstack clouds (among others).

Currently the endpoint URL is hardcoded (see the function below).

/usr/lib/pyshared/euca2ools/commands/eucacommand.py:

    def get_endpoint_url(self, region_name):
        """
        Get the URL needed to reach a region with a given name.

        This currently only works with EC2.  In the future it may use other
        means to also work with Eucalyptus.
        """
        endpoint_template = 'https://ec2.%s.amazonaws.com/'
        endpoint_url      = endpoint_template % region_name
        endpoint_dnsname  = urlparse.urlparse(endpoint_url).hostname
        try:
            socket.getaddrinfo(endpoint_dnsname, None)
        except socket.gaierror:
            raise KeyError('Cannot resolve endpoint %s' % endpoint_dnsname)
        return endpoint_url
