Deprecated metricsInterval Still Present in ConfigMap

While reviewing the Helm YAML files, I was trying to determine the default value for the metricsInterval setting in the ConfigMap. During this process, I found that metricsInterval is already marked as deprecated.

However, it still appears to be present in the ConfigMap. I would like to confirm whether this is being used as a fallback value or if it was unintentionally left behind and should be removed.

Reference:

[ConfigMap YAML in Retina Helm Chart](https://github.com/microsoft/retina/blob/89a07678db8f53d03b4460511e06959659271c60/deploy/hubble/manifests/controller/helm/retina/templates/agent/configmap.yaml#L107)

Could you provide clarification on this?

Thanks!

Start with deploy/hubble/manifests/controller/helm/retina/templates/agent/configmap.yaml around line 107 and trace the metricsInterval setting in the Helm YAML files. Determine whether it is used as a fallback or is obsolete; done means the issue has a clear decision about retaining or removing it.
