WIP - New Logging system

[dregad]

Alternative logging mechanism replacing the current Debug Mode.

Features include:

• Direct integration to any stream supported by the Monolog library. This library is available from Packagist.
• Standardized syslog style file logging that separates different log levels into separate log files
• Provision of messaging in both classic style text and JSON encoded log messages.
• Ability to send additional tags, allowing data filtering in log management software such as Prometheus
• Ability to log only certain levels of messages to improve usability in production environments
• Backwards compatibility with existing ADOConnection::debug features
• Compatible with custom error-trapping functions
• Improved error backtrace logging
