Add REST API for ComponentTemplate CRUD
This adds the Put/Get/DeleteComponentTemplate APIs that allow inserting, retrieving, and removing ComponentTemplateMetadata into the cluster state metadata. These APIs are currently only available behind a feature flag system property - `es.itv2_feature_flag_registered`. Relates to elastic#53101
