--long option breaks in router list if availability_zone ext is not loaded

[Fernando Jalon]

when calling router list with --long OSC expects the availability_zone field in the response, even if this extension is not loaded:

In /usr/lib/python2.7/site-packages/openstackclient/network/v2/router.py if --long is called it's trying to parse availability_zones field:

    def take_action(self, parsed_args):
        client = self.app.client_manager.network

        columns = (
            'id',
            'name',
            'status',
            'admin_state_up',
            'distributed',
            'ha',
            'tenant_id',
        )
        column_headers = (
            'ID',
            'Name',
            'Status',
            'State',
            'Distributed',
            'HA',
            'Project',
        )
        if parsed_args.long:
            columns = columns + (
                'routes',
                'external_gateway_info',
                'availability_zones'
            )
            column_headers = column_headers + (
                'Routes',
                'External gateway info',
                'Availability zones'
            )

        data = client.routers()
        return (column_headers,
                (utils.get_item_properties(
                    s, columns,
                    formatters=_formatters,
                ) for s in data))

    router list if availability_zone ext not enabled

    when calling router list with --long OSC expects the availability_zone
    field in the response, even if this extension is not loaded:

    As per the document, http://developer.openstack.org/api-ref/networking/
    v2/?expanded=list-routers-detail, The availability zone(s) for the router
    is available when router_availability_zone extension is enabled.

    Added testcase to test router list without availability zone
