Report metrics for suggest anomaly detector

[gaobinlong]

Description

This PR implements a small enhancement for the suggest anomaly detector feature, we add feedback button to the flyout of suggest anomaly detector, when users click the button, it will call the metric report API in the core plugin usageCollection. And when LLM gives suggested parameters successfully, a generated metric is reported, when the suggested detector is created, a created metric is reported.

Another change is that we check the feature flag before register the SuggestAnomalyDetector action to Discover, if the feature flag is disabled or the whole assistant capability is disabled, no action will be registered.

Some UI change:

Update the version to v4 to make sure the e2e test can run normally, if not the test throws deprecation error.

@gaobinlong thanks for the change! Just curious, besides this feedback button, are we collecting usage metrics for this flyout? For example, the number of detectors created via this flyout, or errors that occurred on this flyout. If not, do we have plans to add these business metrics?

Thanks, except the feedback metrics, we already add generated metric which reports that LLM has given the suggested parameters successfully, and created metric which reports that the suggested detector has been created successfully, but we haven't collect the failures metrics for this flyout, I'll consider this suggestion seriously and implement it later.
