[FEATURE REQUEST] Import existing Kubeconfig

[aamoyel]

Feature Purpose: Kubeconfig from Kubernetes Secret

Problem Statement

Currently, Kite requires users to manually paste kubeconfig content into the database when adding external clusters. This approach has several limitations:

• Static configuration: Kubeconfigs cannot be updated automatically
• Manual updates: Any change requires manual intervention through the UI
• No GitOps integration: Cannot leverage tools like FluxCD or ArgoCD for configuration management
• No external tooling integration: Becomes tedious when multiple clusters are managed by Cluster API or Sveltos
