The ClientError happened on these lines: https://github.com/mozilla/buildhub2/blob/ac1125d4afd4aa7e83208faf6d44c51849626a18/buildhub/ingest/sqs.py#L58-L62

A simple solution would be to wrap the whole thing in a try:except and do sleeps and retries. Another option is to see if we can increase the number retries from 4 to something like 8 or 16.
