 Description   

Currently migration cleanup returns, after finishing, the number of documents removed - this information isn't sufficient to debug complex performance issues. More information (such as total data removed, avg document size, min/max, etc.) would be helpful for support to debug these issues and would be fairly simple to provide.

Recommend reporting this information periodically as well, as a way of determining status for long-running operations.

will there be log messages at the start and the end of each deletion?
