MINIO_ETCD_COMMENT          (sentence)  optionally add a comment to this setting

This behavior is consistent across all keys; each key self-documents itself with valid examples.

Download a file, print its headers, and print its response body as a string.

The `string()` method on response body is convenient and efficient for small documents. But if the response body is large (greater than 1 MiB), avoid `string()` because it will load the entire document into memory. In that case, prefer to process the body as a stream.
