Default translation for Erlang log messages.

Logger allows developers to rewrite log messages provided by OTP applications into a format more compatible with Elixir log messages by providing a translator.

A translator is simply a tuple containing a module and a function that can be added and removed via the Logger.add_translator/1 and Logger.remove_translator/1 functions and is invoked for every Erlang message above the minimum log level with four arguments:

• min_level - the current Logger level
• level - the level of the message being translated
• kind - if the message is a :report or :format
• message - the message to format. If it is :report, it is a tuple with {report_type, report_data}, if it is :format, it is a tuple with {format_message, format_args}.

The function must return:

• {:ok, chardata, metadata} - if the message translation with its metadata
• {:ok, chardata} - the translated message
• :skip - if the message is not meant to be translated nor logged
• :none - if there is no translation, which triggers the next translator

See the function translate/4 in this module for an example implementation and the default messages translated by Logger.
