The second line of warning may need to be ignored temporarily, because this extension is work-in-progress in envoy (#1966 (comment)). Maybe I can fix other warning Message?

[zirain]

can we fix the second one with static_layer like istio did?

[tmsnan]

can we fix the second one with static_layer like istio did?

Runtime key overload.global_downstream_max_connections is deprecated and will be removed in future, maybe we need to raise an issue in envoy.
