Typo in several modules fixed

FYI, LM pushed out a bunch of modules containing a typo in one of the tokens in the alert message. ##DESCRIPTION## isn’t a valid token and ##DSIDESCRIPTION## should be used instead. This has been corrected in the following modules:

• Aruba_ClearPass_AccessAuthorization
• Aruba_ClearPass_DiskMemoryUsage
• Aruba_ClearPass_NetworkTraffic
• Aruba_ClearPass_PolicyServer
• Aruba_ClearPass_ProtocolStats
• AWS_ElasticTranscoder
• CiscoSLA_jitter-
• Logstash_ConfigReload_Stats
• NetApp_7mode_SnapshotScheduler
• OpenGear SerialPort
• VMware_ESXi_HardwareHealthSensor
• VMware_vCenterAppliance_Backup
• VMware_VCSA_BackupInstances
• Whois_TTL_Expiry
