the max value of 'max_request_bytes' is not match

We have a problem when load the file envoy.yaml to xds developing based on this project. The max value in envoy.yaml is 4294967295, but the max value in this project is 2147483647 (Java's Int type).

The content in envoy.yaml as follows:

          http_filters:
          - name: envoy.ext_authz
            typed_config:
              "@type": type.googleapis.com/envoy.extensions.filters.http.ext_authz.v3.ExtAuthz
              http_service:
                server_uri:
                  uri: 10.160.78.3:1001
                  cluster: ext-authz
                  timeout: 1s
              failure_mode_allow: false
              with_request_body:
                max_request_bytes: **4294967295**
                allow_partial_message: true

but when load the content to xds, the value exceeds the max value of Java's Int type.

[api/src/main/proto/envoy/config/filter/http/ext_authz/v2/ext_authz.proto] uint32 max_request_bytes ;

uint32 corresponds to int in Java and int32 in Go, so this will result in an error when load the envoy.yaml.

Yes, you are right.

I think this is not the side of envoy/envoy control problem, the really peoblem is really need to set the max value?
