Add "debug" and "quiet" flags

These flags aim to control the logging level [1] of virt-bootstrap.

Default = INFO (Confirmation that things are working as expected)

--debug = DEBUG (Detailed information,
                 typically of interest only when diagnosing problems)

--quiet = WARNING (An indication that something unexpected happened,
                   or indicative of some problem in the near future)
