Issues found in Cinder /os-hosts API

[Feilong Wang]

There are some issues found in Cinder /os-hosts API.

1) Bracket in the wrong spot in Cinder HostController show method
   There is an erroneous bracket on the following line in the show method that shoudl be at the end of the response:
     'total_volume_gb': str(sum)},

2) XML Attributes Missing for List/Index method in Cinder HostController
   The HostIndexTemplate class specifies mapping for "host" and "topic" attributes rather than any of the ones that are actually returned from the index method. This needs to be updated to map host_name, service, zone, service-status, service-state and last-update attributes

3) XML Serialization Not Implemented for Cinder HostController show method
   The "wsgi.serializers(xml=HostShowTemplate)" decorator is commented out on the show method, so this doesn't end up allowing XML to be be fully returned for additional attributes added. This needs to be uncommented
