feature: add interval on AI backend request

This commit introduces the ability to send the requests to the backend
AI server at set intervals, independent of the reconciler's requeue
requests.

To utilize this feature, the `Interval` field in the `AI` settings must
be set in the k8sgpt configuration object. Also, the specified interval
must be greater than or equal to the reconciler's requeue interval as
the llm requests should be called after the reconciler executes k8sgpt
analyze.

Fixes: #419
