Make informative output for pytest --help

[NickVolynkin]

qase-pytest==5.0.5 returns the following output for pytest --help:

 log_level (string):   Default value for --log-level
  log_format (string):  Default value for --log-format
  log_date_format (string):
                        Default value for --log-date-format
  log_cli (bool):       Enable log display during test run (also known as "live logging")
  log_cli_level (string):
                        Default value for --log-cli-level
  log_cli_format (string):
                        Default value for --log-cli-format
  log_cli_date_format (string):
                        Default value for --log-cli-date-format
  log_file (string):    Default value for --log-file
  log_file_level (string):
                        Default value for --log-file-level
  log_file_format (string):
                        Default value for --log-file-format
  log_file_date_format (string):
                        Default value for --log-file-date-format
  log_auto_indent (string):
                        Default value for --log-auto-indent

In fact, all help strings are available in qase-pytest/src/qaseio/pytest/options.py, but not passed to the output. We should fix it.
