Today, we cannot dynamically configure the Envoy configmap to target the host IP.

Describe the solution you'd like
In our Envoy wrapper dockerfile: https://github.com/solo-io/solo-projects/blob/18a7aa

Right now we have some basic information about how to get involved under https://projectcontour.io/community/. I think we could drive more attention to the community efforts if we had a more prevalent "Get involved" section on the front page, similar to what https://inclusivenaming.org/ does.

An example of this is #224. We wanted to handle the case where re-auth failed 3 times, but there was no good way of bubbling up the error to main.go. We could make reconciler.Run return an error to bub

I'd like to see proxy_get_buffer_status(), e.g. https://github.com/proxy-wasm/proxy-wasm-cpp-host/blob/92f02c0001592199d99f946cea34637ff095a8ba/include/proxy-wasm/wasm_api_impl.h#L147

Also proxy_get_header_map_size() , e.g. https://github.com/proxy-wasm/proxy-wasm-cpp-host/blob/92f02c0001592199d99f946cea34637ff095a8ba/include/proxy-wasm/wasm_api_impl.h#L192
