This object is used to create and delete threshold templates.
The values of cifthTemplateName and
cifthTemplateNotifyHoldDownType must be provided before
activating the entry.
An entry can only be deleted when there are no active entries
in the cifthTemplateIfAssignTable with the same value of
cifthTemplateIndex.
When an entry is deleted, all associated entries in the
cifthThresholdTable are also deleted.
After the entry has been activated, this object cannot be set
to any value other than 'destroy'. The row status never
changes to 'notInService' after reaching the value 'active'.
