SessionAffinityConfig describes different affinity configurations for new sessions. Once a session is mapped to a backend based on some affinity setting, it retains that mapping till the backend goes down, or the ingress controller restarts. Exactly one of these values will be set on the upstream, since multiple affinity values are incompatible. Once set, the backend makes no guarantees about honoring updates.
