When an HTTP/2 server retires a connection with GOAWAY after it has
already sent successful response headers, Go's http2 transport fails the
read of the response body with
http2: server sent GOAWAY and closed the connection; LastStreamID=..., ErrCode=NO_ERROR, debug=""
This was not recognised as a retriable networking error, so a transient
connection retirement aborted the whole command instead of consuming a
low level retry. It was reported against a large S3 check, where an
interrupted ListObjectsV2 page made rclone report destination objects as
missing and exit unsuccessfully.
The concrete error type is unexported by net/http, so match on the
message as we already do for the other http2 transport errors.
