Optional Backup Summary to the log

[Massimo-B]

Hi, please provide an option to add the useful Backup Summary also to the logs.

The btrbk client prints the summary like this:

--------------------------------------------------------------------------------

Legend:

If you invoke btrbk as root, you could add >> /var/log/btrbk.log Example : /usr/bin/btrbk run >> /var/log/btrbk.log
