Resolve issue #1
Updated the sender item keys in the Zabbix template to account for a new unique value. This new unique value is similar to a key in SQL so that the correct value can be pulled from the discovery cache on the discovery server. This only needs to be done for senders as the discovery cache will not discover duplicate items for the other discovery rules.
