An additional mitigation to CVE-2023-44487 available in Envoy 1.27.1. This change allows configuring the http.max_requests_per_io_cycle Envoy runtime setting via Contour configuration to allow administrators of Contour to prevent abusive connections from starving resources from others. The default is left as the existing behavior, that is no limit, so as not to impact existing valid traffic. See the Envoy release notes for more information: https://www.envoyproxy.io/docs/envoy/v1.27.1/version_history/v1.27/v1.27.1 Signed-off-by: Sunjay Bhatia <sunjayb@vmware.com>

Adds a global Listener configuration field for admins to be able to protect their installations of Contour/Envoy with a limit. Default is no limit to ensure existing behavior is not impacted for valid traffic. This field can be used for tuning resource usage or mitigated DOS attacks like in CVE-2023-44487. Also fixes omitempty tags on MaxRequestsPerIOCycle field. Fixes: projectcontour#5846 Signed-off-by: Sunjay Bhatia <sunjayb@vmware.com>
