[Logs UI] Mark Log Stream for deprecation

[tonyghiani]

📓 Summary

Closes #184992

Due to Logs Explorer and Logs being 2 separate apps, it was more complicated to redirect the Logs default nav menu to Logs Explorer maintaining the same hierarchy on both the sidebar and the global search.
The implemented workaround redirects from the logs app to logs explorer once the main app route for logs UI is accessed, which should keep all the previous behaviours.

I think I wasn't really precise about this, sorry - I meant the beta tag should be on the "Logs" entry in the main nav menu (as it leads to the logs explorer, which is beta), not on the "Logs" section in the Observability menu.

I think it's OK to keep it on the "Explorer" entry on there.

In this case, it might not be a quick win because the sidebar entry is displayed using the app registration title, which does not support adding a beta badge or any other custom react node (the same value is used by the core application app to register the global search entry).

I can move back the Beta badge next to the Logs Explorer entry, but I don't think there is something quick we can do for a badge in the main sidenav entry, given the time constraint for 8.15.

Ah, wasn't aware we couldn't control this easily. OK, let's move it back then, I think it's OK that way

[tonyghiani]

@mdbirnstiehl could you please take a look at the copies for this work? Would be great if we can merge it before the feature freeze for 8.15 of next week.

[mdbirnstiehl]

I had a few suggestions. Let me know if you have any issues or questions.

[tonyghiani]

@mdbirnstiehl thanks for the suggestions! We'll also need to update the documentation with a deprecation warning on the tail logs page, do you think we should use a different callout content for that? Could you help with the change on the docs please?

[flash1293]

This is how the callout looks right now:

@mdbirnstiehl Do we need both of the paragraphs? Seems like we can shorten it to a single one. Also, it says Logs Explorer a lot, reads a bit weird to me.

Also, the bit about support could be interpreted that we don't support it anymore right now which isn't true, maybe "will be replaced by Logs Explorer in a future version" or something like that?

@flash1293 We could reduce it like this:
The new Logs Explorer makes viewing and inspecting your logs easier with more features, better performance, and more intuitive navigation. We recommend switching to Logs Explorer, as it will replace Logs Stream in a future version.

Love it, @mdbirnstiehl !

Callout looks good to me, why did you remove a bunch of tests @tonyghiani ? It seems like it shouldn't change anything in that area?

It affects those tests because they were oriented on loading the logs app landing page, which corresponds to app/logs and then redirected to app/logs/stream .

As we now have a redirect to app/observability-logs-explorer, those tests were all broken/unnecessary because we don't go through that flow anymore.
