Updated the Rackspace Monitoring Alarm example criteria so that it shows a brief diagnostic summary if there was a backup error.
Monitoring checks were flapping due to the JSON data not being properly parsed with grep. Used python to read data instead.
Fixed the logic so that it shows the Cloud Backup Report of a given BackupConfigurationId (third parameter).
Force user to specify a BackupConfigurationId parameter if multiple Backup Configurations were detected.
Set default values for the output metric variables if the corresponding variables didn't have data. Fixes alerts being triggered due to an unexpected empty variable.
