[jira] [Created] (HDDS-14701) Consolidate DiskBalancerVolumeChoosingPolicy and ContainerChoosingPolicy

Sammi Chen created HDDS-14701:
---------------------------------

             Summary: Consolidate DiskBalancerVolumeChoosingPolicy and ContainerChoosingPolicy 
                 Key: HDDS-14701
                 URL: https://issues.apache.org/jira/browse/HDDS-14701
             Project: Apache Ozone
          Issue Type: Sub-task
            Reporter: Sammi Chen
            Assignee: Gargi Jaiswal


We have DiskBalancerVolumeChoosingPolicy#chooseVolume to choose a pair of {sourceVol, destVol}, and then have ContainerChoosingPolicy#chooseContainer to pick one container from sourceVol to destVol.  In each function, overall ideal utilization and specific disk utilization are calculated individually to serve the logic. 

Consolidate two functions into one(chooseContainer) will avoid some recalculation. 
And 5GB is used as the container size when choosing destVolume, while a specific container is picked, it's better for us to adjust destVolume's with container's real size, which could be larger than 5G, or less than 5G.
