    [FEATURE] Configure rate limit service image location

    I was looking at the RateLimitService CRD and it looks like you've hardcoded the rate limit service image to be pulled from zufardhiyaulhaq/ratelimit:v1.0.0 I did try specifying the container just to test out my theory

         "container" = {
              image             = "${MY_AWS_ACCOUNT_ID}.dkr.ecr.us-east-1.amazonaws.com/envoyproxy-ratelimit:8d6488ea"

              command           = ["/bin/ratelimit"]
            }
    
    

    Can you verify that my assessment is correct or I've missed something. Thanks

    [FEATURE] shadow_mode support

    Any ideas or possibilities in the roadmap to support the latest release of ratelimit by the original repository of envoy proxy? Nowadays the HEAD git repository has the support of shadow_mode, this could be handy to include the ratelimit rules but without enforcing, only checking if the ratelimit will be aggressive, generate some kind of impact in the production environment If there is some kind of possible test that I could do, I would be glad to help

    Is your feature request related to a problem? Please describe. We need to provide ratelimit by path or method (put for example) on the application and not for the entire application.

    Describe the solution you'd like my config should look like the following example:
