maybe "cannot create external storage before init"?

Done.
…r struct Previously, we initialized the ExternalStorage factory methods on creation of a NewServer() as all the required config params were ready-to-use. With future work related to user scoped storage requiring access to the underlying storage.Engine, this change introduces a wrapper around these factory methods. Using a builder struct allows us to split the "creation" and "initialization" of the builder between the NewServer() and Start() methods respectively. This allows for params which are only initialized on server.Start() to be propogated to the builder for future use. This is part of a gradual refactor of the ExternalStorage factory interface and is primarily to unblock development of cockroachdb#47211. Release note: None
