[FEATURE] Add Karpenter example

[nabuskey]

Is your feature request related to a problem? Please describe

We have added example for Cluster Autoscaler, and I think it's a good idea to add an example for Karpenter.

Describe the solution you'd like

Add compositions and examples for creating EKS clusters with Karpenter. This must be done in the upbound provider because the community provider does not support necessary cloudwatch resources.
