Kubernetes > Adding existing EKS cluster > Reduce redundant docs
We currently have https://docs.gitlab.com/ee/user/project/clusters/#add-existing-kubernetes-cluster, which tells the user how to get the necessary fields needed to add an existing cluster to GitLab.
We also have a specific page dedicated to adding an EKS cluster: https://docs.gitlab.com/ee/user/project/clusters/eks_and_gitlab/
The steps for getting the necessary fields to add the cluster are slightly different on each page. We should consolidate https://docs.gitlab.com/ee/user/project/clusters/eks_and_gitlab/ since the general docs page uses less steps. Better yet, we can just link to the steps for getting those fields to keep our docs DRY.
There are other sections on this docs page that may not need to be there either. For example, installing applications.
Proposal
Audit https://docs.gitlab.com/ee/user/project/clusters/eks_and_gitlab/ and only include relevant information related to EKS. Link to the global documentation where necessary to keep docs DRY.
