AWS CloudWatch logs for Container Insights contain no CPU usage metrics when setting collection_interval to more than 300s

What happened?

Description

We've tried to increase the collection_interval parameter for the receivers.awscontainerinsight component to optimize AWS CloudWatch costs.

I've figured, that it is related to the TTL in the map used to store metric deltas: when the collection interval is more than 5 minutes, collecting deltas breaks because older deltas get removed before new deltas are applied.

Increasing the cleanInterval to 15 minutes helps.

Steps to Reproduce

1. Create any EKS cluster
2. Install OTEL to collect AWS Container Insights
3. Set receivers.awscontainerinsightreceiver.collection_interval to 600s
4. Restart the daemonset
5. Wait for 15-20 minutes

Expected Result

Log events in CloudWatch contain CPU usage metrics

Actual Result

Log events in CloudWatch do not contain CPU usage metrics

Collector version

0.41.1
