CAIQUM-221：启用时、ActiveIQ Unified Manager卷运行状况阈值警报会考虑自动增加最大大小

问题描述

The threshold calculation on volumes considers Autogrow Max Size if autogrow is enabled.
For such volumes (assume it has 5% snapshot reserve) where autogrow is enabled, it considers 95% of the Autogrow Max Size as volume total data capacity
When autogrow is disabled, it considers the actual volume total data capacity for volume events.
