The CTest item
* update_bindings_go_src_fdb_generated_go
will compare the generated go api with hardcoded go api to test the
generation. New FDB option will cause hardcoded go code outdated.
In the current code, errors are retried in getConsistentReadVersion, so it's
possible that the client has cancelled the GRV request, but readVersionBatcher
continue retrying, which can lead to many clients DDoS GRV proxies, especially
when the database has become unavailable for a while and clients are issuing
many GRV requests.
