Added functionality to log_file_verbose. However, the default value does not work.

 If you need to record the whole test suite logging calls to a file, you can pass
 ``--log-file=/path/to/log/file``. This log file is opened in write mode by default which
 means that it will be overwritten at each run tests session.
+You can specify the level of verbosity of the log file by passing ```--log-file-verbose=1``
 If you'd like the file opened in append mode instead, then you can pass ``--log-file-mode=a``.
 Note that relative paths for the log-file location, whether passed on the CLI or declared in a
 config file, are always resolved relative to the current working directory.
