[EKS] [request]: Add a button console for the aws eks update-kubeconfig command

The EKS console should add a button on EKS pages near the cluster name that shows the instructions to run the `$ aws eks update-kubeconfig` command. For example, the button says "Connect". When clicked, it generates the following command and shows in a pop-up:

```
$ aws eks update-kubeconfig --name=CLUSTER --region=REGION
```

No repository files or tests are named. Start by reviewing the EKS pages around the cluster name and define the Connect button and pop-up behavior; done means the pop-up displays an aws eks update-kubeconfig command using the selected cluster and region.
