Allow logs endpoint to ingest `cluster_id` parameter, and respond with gitlab managed apps logs

Background

Currently Logs explorer allows users only to monitor logs collected from environments based namespaces within their clusters.
With #208790 (closed) we want to extend logs explorer usability, by adding ability to view logs collected from gitlab-managed-apps namespace, which host different GitLab Managed Applications

What does this MR do?

This MR extends logs controller, with cluster_id parameter, based on it, one of clusters available to project is selected, and logs for gitlab manage apps are fetched.
