Flow UI: Component page could show recent logs

[tpaschalis]

In the future, the Flow UI could be used to display the recent logs (~5 minutes?) emitted by a component in its details page.

Since Flow has a better story around a shared logging interface, and by default all components log in a different stream, it might be easier to do than expected. We might have to alleviate some concerns around security, but by default the UI is only exposed on localhost so I don't think it's more of a risk than the normal logging in a Kubernetes environment for example.

When debugging an Unhealthy component, the extra hints alongside its configuration and dependents could be useful.

Assuming we can have some controls around it, this sounds extremely solid idea.

Are you imagining a stream of logs or only showing the last 5 minutes of logs from the time the page is loaded?

Also: ~minutes of logs might be an issue for extremely noisy components. What about the last N logs (like 100)? (Or even last X minutes up to N maximum logs?)

Good point about noisy components, we'll figure out a way to trim this down.

A stream of logs would that is enabled on demand would be the best, but even a static view of the last N logs kept in a queue would be a good start.
