[DPE-1928] Update lib

[zmraul]

Update with the changes from data_platform_libs on KafkaRequires and add an integration test on wildcard usage.

Only the test needs review.

Uhm, could we handle the error and rather put the charm into blocked state (with a sensible message) should the validation for the topic name not pass?

We can do that, but I was letting it fail on purpose as a way of also stopping all events from triggering.

But the relation would be created anyway in the juju model, right? I mean, you would only stop anything from happening at the data-integrator side I suppose. We could always put the charm into a blocked status and then allow the user to change the configuration (topic_name) and if the user then provides sensible values (with juju config and handling config_changed events), then everything solves by itself, since the relations are already in place

Not exactly, KafkaRequires is invoked in the init method. Since we don't update relation databag, the config information is not being used on kafka side either. But I see that this is creating some unexpected outcomes, as I don't think setting status on init is a good option.

Changes look all right, but let's trigger the discussion of handling validation inside and outside DataPlatform to understand the long-term solution. But fine to be merged for the time being.

There are a number of failing integration tests although, that needs to be fixed before merging.
