Improve getting information about questions

[cortadocodes]

Feature request

Use Case

Improve the visibility of question statuses (running, failed, finished etc.) and what's currently going on (logs, monitor messages, diagnostics). Also clean up and simplify the code for checking this.

Current state

The event replayer, get_events function and octue get-diagnostics are disparate and a bit of a pain to use.

Proposed Solution

• Add a function and CLI command returning a question's status
• Move octue get-diagnostics inside octue question command
• Avoid having to call event replayer and get_events function
