feat(securitycenter): add canonical_name and folder fields
  Assets and findings may be created in organizations, folders or projects, however in the current API version the name field for resources will always be prefixed by "organizations/...", for historical reasons. The "canonical_name" field shows the actual location of the resource, and in requests either the name or "canonical name" can be used for the "name" in the request.

  The "folder" field contains the folders in the resource's ancestry.
