Integrate OpenAI into the chat bot #8.

[iramykytyn]

Changes description

• Adds /message endpoint for slack message events.
• Adds OpenAI integration for chat completion. Implements OpeanAI configuration from JSON file.
• Adds unit tests. Updates CI to run tests with coverage and post coverage report as PR's comment.
• Fixes version check CI.
• Updates README with instructions on how to setup the slack app.

What else do I need to know?

Added a few TODOs in the code to be implemented later:

• Messages should be streamed if possible to do it with slack or user should be notified somehow that the response generation is in progress.
• Logging should be refactored to be configured from one place and stored to the file.
• Add deployment instructions and make deployment run automatically from CI.
