[aws-eks] eks.Cluster.fromAttributes: Allow adding k8s resources on imported clusters

Currently I have an existing EKS cluster, is that possible to call addResource from another pipeline or someplace?

Use Case

I tried to use fromClusterAttributes, but it only returns a ImportedCluster which does not have any static method.

It will be good to have:

const cluster = new eks.Cluster.fromClusterAttributes(this, 'eks-cluster', {...});
cluster.addResource('ingress', {...});
cluster.addResource('service', {...});

In my case we have multiple repositories and each of them creates different part of infrastructure using CDK. Some repo needs to create an eks fargate profile o apply some manifest through addResource method to a same cluster. Is there any workarround for this since we can’t import the cluster for every repo and use this kind of methods? (creating a cluster for every repo would be over dimensioned). It would be a great feature.

Another problem we have find out related to this issue is that using addResource method from different stacks in the same app (passing the cluster as argument to the stack that calls addResource) the cloudformation resource is actually created on the stack where the EKS Cluster was created instead of the stack where the addResource was called. This wouldn’t be a problem itself if Cloudfromation didn’t have the 200 resource limit per stack. We have reached this limit because all the stacks are almost empty and all k8s resources are created on the stack where the cluster was created. We don’t know how to solve this problem unless every stack could import the cluster and call addResource and create the cloudformation resource separately.
