Make logs configurable via environment variables

[Anton0C]

Description:

It would be useful to make the logging behavior of the application configurable. Specifically, I would like to:

1. Change the verbosity of logs (e.g., INFO, DEBUG, ERROR).
2. Enable or disable JSON output for logs.
3. Pass custom log format strings.

All of these configurations should be adjustable via environment variables to provide more flexibility in different environments.

Suggested environment variables:

• LOG_LEVEL: Set the logging verbosity level (e.g., INFO, DEBUG, ERROR).
• LOG_ENCODER: Enable plain text or JSON logging output (plain or json).
• LOG_FORMAT: Ability to customize the content of each log string.
