The `nova-manage db archive_deleted_rows` command doesn't print any
results, not even how many rows were deleted, which is something the
database API returns.
The number of rows deleted also changes depending on the max_rows input
and how many rows are deleted in each table, it's a cumulative effect.
We should keep track of which tables we've deleted rows from along with
how many rows, and print that all out to the CLI console if the user
passed a --verbose option.
