Tests are flaking flake when kgo-repeater dies with a non-retriable error right after connection. This happens when franz-go gets EOF right after connecting but before receiving any response, as a heuristic it assumes this is a SASL misconfiguration as that is the broker behavior in that case. However, this can also occur because Redpanda is stopped/killed after the connection is made but before the initial requests can be responded to. This means the producer will fail if a producer dies/is killed/stops during a critical window between the connection and receiving the first response. This is reasonably likely in stress/chaos tests where producers are being started and stopped all the time. This is a relatively recent change (~6 months ago) in franz-go, which was brought in a few months ago by a franz-go upgrade. To fix this, we make use a proposed new option to franz-go, from this PR: twmb/franz-go#1198 This is not merged, so we pull in the SHA from this PR directly. When a franz-go release is made with this change, we can update to that. Details in CORE-14849. Fixes CORE-14898.
