Instead of shuffling perhaps use rand.Perm ? It's shorter syntax and conveys better what we want to accomplish

Yes, that's definitely neater. Thanks.
In the Submit() API method, the list of available orderers has been randomized to support improved load balancing. Retry logic has been added such that if the selected orderer fails to return a success code, then the next orderer in the list is tried. If no orderers succeed, then return an error (containing details from each orderer) to the client. Signed-off-by: andrew-coleman <[email protected]>
