Hi!

I use PATCH requests that go through envoy and logs are written with als implemented on golang. I expect to see "PATCH" as a result of this code:

import (
	envoy "github.com/envoyproxy/go-control-plane/envoy/data/accesslog/v2"
)

func RequestMethod(ent *envoy.HTTPAccessLogEntry) string {
	return ent.GetRequest().GetRequestMethod().String()
}

Instead, I see "METHOD_UNSPECIFIED". When I tried to find the reason in the library code, I found that PATCH is not in the list of request methods (https://github.com/envoyproxy/go-control-plane/blob/master/envoy/api/v2/core/base.pb.go#L67)

What do you think about this? Was it omitted intentionally or just missed? Can it be the reason of the problem I described?

Thank you for your help.
