 Review comment:
   Instead of `String` can we use `HddsVolume` as method argument?
   Then we can also rename the method to `public Iterator<Container> getContainers(HddsVolume

> Ozone data scrubber needs to start a dedicated thread per volume to perform checksum
validation for all the containers in the given volume. But currently ContainerController does
not expose an API to fetch the list of containers for a given volume. This Jira is to add
the relevant API to ContainerController class so that we can retrieve list of containers for
a given HDDS volume.
