feat: add troubleshooting section to monitoring and logging

[valyria257]

Proposed changes

NGINXaaS now provides events to users in case of failures exporting logs and metrics to Google Cloud. This adds a troubleshooting section to the logs and metrics pages with instructions on how to view these events.

I'm thinking once the events page starts showing more events and it turns more into an Activty Log, we can have a separate page with more details.

Since I don't have access to this console, I can't give this a complete review. So I've some basic readability suggestions.

Question: is there a way to review metrics from the CLI? If so, I'm guessing our users might prefer that method.

Sounds good! I also put a screenshot of what the Events page looks like in the PR description in case that helps.

I don't think there's a way via the CLI. Google's documentation on reading metrics says that the three methods are through the Google Cloud console, the API, and different language-specific client libraries. We currently have examples of using the console and the API, but none of any libraries (not sure how populate those are).
