Indicating the limit of transfers to/from cold storage in the CLI

[psaiz]

The stage/archive functions to move data between cold and hot have two ways of limiting the number of files:

• --limit X: Number of files of the record that will be checked
• --transfers Y: Maximum number of transfers that should be issues\

The CLI has a parameter for the first one, and not for the second. The second is only used at the moment from the automatic task.

The CLI should also allow the --transfers, both for the stage and the archive
