If the error type is `*RemoteErr`, then the error was returned by the remote server. Otherwise it is a local error.

Context timeouts are propagated, and a default timeout of 1 minute is added if none is specified.

There is no cancellation propagation for single payload requests.
When the context is canceled, the request will return at once with an appropriate error.
