Add a new subcommand 'kustomize edit add configuration' to programmatically add configuration file references to kustomization.yaml files. This brings configurations support in line with other 'kustomize edit add' subcommands (generators, transformers, validators). Features: - Support for single and multiple configuration file paths - Glob pattern expansion (e.g., ./configs/*.yaml) - Duplicate detection with user logging - Idempotent operation Related to https://github.com/kubernetes-sigs/kustomize/issues/5987
