heat : Remove cloudwatch functionalty from metadata server
Remove the cloudwatch metric functionality from the heat-metadata
service, since all stats should now be sent via the CloudWatch
api via the PutMetricData action (ref cfn-push-stats update)
Note that after this change you will need to rebuild your jeos
images to get the new version of cfn-push-stats from heat-jeos
