TTL indexes are shown as unused

[kagahd]

According to mongoDB's documention, the statistics [reported by the $indexStats aggregation] only includes index access driven by user requests. It does not include internal operations like deletion via TTL Indexes or chunk split and migration operations.
See also: https://jira.mongodb.org/browse/SERVER-21815
Therefore, in Maobi, in section 1.1.5 Unused Indexes (mongod up > 7 days), you may see "unused" indexes which in fact may be TTL indexes and as such are not unused.
Suggestion: Maobi should take into account TTL indexes and not show or count them as "unused".
