HDDS-9950. 'ozone fs -ls' on volume shows the volume owner as the bucket owner

[xBis7]

What changes were proposed in this pull request?

When doing a listStatus on a volume, we are setting the volume owner as the resource owner. Therefore, ozone fs -ls is resulting in displaying the volume owner as the owner of every bucket.

Check the jira description for a test-case for manually reproducing it.

How was this patch tested?

A new test was added under TestRootedOzoneFileSystem. The patch was also tested manually in ozone docker dev env like so

> pwd
/projects/ozone/hadoop-ozone/dist/target/ozone-1.5.0-SNAPSHOT/compose/ozone

  // Start docker env
> docker-compose up --scale datanode=5 -d

  // Create volume with the default user, hadoop
> docker-compose exec om ozone sh volume create /vol1

  // Create bucket and set the owner as testuser
> docker-compose exec om ozone sh bucket create /vol1/bucket1 --user testuser 

  // Create bucket and set the owner as testuser2
> docker-compose exec om ozone sh bucket create /vol1/bucket2 --user testuser2 

  // fs -ls
> docker-compose exec om ozone fs -ls /vol1
