Description

Use case: For capturing point-in-time Ozone snapshot referenced size (See HDDS-7743).

Right now we only counts replicated size in OmBucketInfo:

https://github.com/apache/ozone/blob/ed6f046c18f5f1a542aacfb7effe3174eba3b3af/hadoop-ozone/ozone-manager/src/main/java/org/apache/hadoop/ozone/om/request/key/OMKeyCommitRequest.java#L248

      long correctedSpace = omKeyInfo.getReplicatedSize();

We can add another metric to count omKeyInfo.getDataSize() instead.
