      Description

      HDDS-1163 takes a simplistic approach to deal with concurrent block deletes on a container,
      when the metadata scanner is checking existence of chunks for each block in the Container Block DB.

      As part of HDDS-1663 checkBlockDB() just does a retry if any inconsistency is detected during a concurrency window. The retry is expected to succeed because the new DB iterator will not include any of the blocks being processed by the concurrent background delete. If retry fails, then the inconsistency is ignored expecting the next iteration of the metadata scanner will avoid running concurrently with the same container.

      This Jira is raised to explore a more predictable (yet simple) mechanism to deal with this concurrency.
