Code Issues Proposed changes

Verify archive_deleted_rows --all-cells in post test hook 

We are already running archive_deleted_rows in the gate, but we are
not verifying whether all instance records, for example, were actually
successfully removed from the databases (cell0 and cell1).

This adds the --all-cells option to our archive_deleted_rows runs and
verifies that instance records were successfully removed from all cell
databases.

It is not sufficient to check only for return code 0 because
archive_deleted_rows will still return 0 when it misses archiving
records in cell databases.
