Added new config ``[logging]log_formatter_class`` to fix timezone display for logs on UI

If you are using a custom Formatter subclass in your ``[logging]logging_config_class``, please inherit from ``airflow.utils.log.timezone_aware.TimezoneAware`` instead of ``logging.Formatter``.
For example, in your ``custom_config.py``:

.. code-block:: python
   from airflow.utils.log.timezone_aware import TimezoneAware

   # before
   class YourCustomFormatter(logging.Formatter):
       ...


   # after
   class YourCustomFormatter(TimezoneAware):
       ...


   AIRFLOW_FORMATTER = LOGGING_CONFIG["formatters"]["airflow"]
   AIRFLOW_FORMATTER["class"] = "somewhere.your.custom_config.YourCustomFormatter"
   # or use TimezoneAware class directly. If you don't have custom Formatter.
   AIRFLOW_FORMATTER["class"] = "airflow.utils.log.timezone_aware.TimezoneAware"
