Instance clusters API (certificate-based) (deprecated)

DETAILS: Tier: Free, Premium, Ultimate Offering: Self-managed

WARNING: This feature was deprecated in GitLab 14.5.

With instance-level Kubernetes clusters, you can connect a Kubernetes cluster to the GitLab instance and use the same cluster across all of the projects within your instance.

Users need administrator access to use these endpoints.
