EKS

Tell us about your request
CloudWatch Container Insights for EKS should have an option for excluding some of the metrics which are not required in order to save the cost of custom metrics.

Configurations
Ability to select which metrics to exclude such as pod_network_rx_bytes, pod_network_tx_bytes, etc.

No repository files, tests, or implementation entry points are identified in the issue. Start by reviewing the requested EKS Container Insights behavior and the listed metrics, then define how users would select exclusions and how completion would be verified against CloudWatch ingestion and custom-metric costs.
