cc-logs: add a breakpoint mode on the filter

[pdesoyres-cc]

Context

• you search for a specific log but you don't know when it occurred
• you go to the last 7 days view
• you type the thing you're looking for in the filter input
• and you see that logs are loading, but with the filter, nothing is displayed on the log panel
• after a certain amount of time, you can see a log matching the filter... hurray!
• but the logs are still loading
• after a certain amount of time, you see your matching log disappear because of the hard limit that the component can handle.

This happens because the filter is handled on client side.

Idea

We could have a mode where the log stream is paused every time a log matches the filter.

We could add a toggle button somewhere close to the filter input that when activated, works a little bit like a breakpoint.

Alternatives

We could play the filter on server side, but there will be some annoying side effects like:

• the stream would be replayed from the beginning every time the filter is changed
• the filtering would not be as fast as now (in memory filtering is fast)
