Description

Support has been added in Recon to track namespace summaries for FSO backed data. From HDDS-5362, a bucket has a 'type' according to which how it stores it underlying data varies. The existing NamespaceSummary task already works only for FSO buckets since it tracks updates into only the FILE and DIRECTORY tables.

In this JIRA, we can add a task that listens on KEY table, and tracks summaries for Legacy OS buckets. Since this is an Object Store bucket, we do not need to track 'du' information for now. We can just track file size distribution and number of prefixes/keys under this prefix.
