**Tell us about your request**

Implenetation of Multidimentional Pod Autoscalling for EKS.

**Which service(s) is this request for?**
EKS

**Are you currently working around this issue?**

Currently I didn't found any workaround because you can use VerticalPodAutoscalling or HorizaontalPodAutoscalling for pods ... can't use both.

**Additional context**

Such kind of feature is implemented in GKE.

Documentation from GoogleCloud about MPA feature in GKE:

https://cloud.google.com/kubernetes-engine/docs/how-to/multidimensional-pod-autoscaling#using_multidimensional_pod_autoscaling

Start by reading the linked Google Cloud documentation on multidimensional pod autoscaling and comparing its behavior with EKS. Review the current EKS documentation for VerticalPodAutoscaling and HorizontalPodAutoscaling. Done means the requested multidimensional autoscaling capability is defined and available for EKS, with its interaction with both existing autoscalers documented.
