feat(metrics-operator): update controller logic to support multiple metric values

[rakshitgondwal]

Fixes #2083

Information

This PR modifies the metrics controller logic to support multiple metrics in its status field.
If a user has specified the metric.spec.range.storedResults field with n (n can be <= 255), the user will be able to see a slice of n number of metrics under metric.status.intervalResults.
