Allow configurable resource requests and limits received by helm chart.

[musa-asad]

Description of changes:
Receive the new auto-instrumentation-config command argument and apply those values to resources for init containers to have resource limits.

Testing:

1. Built the operator changes into an image stored in ECR.
2. Made changes to the helm chart, here.
3. Locally updated the helm-charts/charts/amazon-cloudwatch-observability/templates/operator-deployment.yaml to include the new image stored in ECR.
4. Created an EKS cluster.
5. Ran kubectl apply -f helm-charts/charts/amazon-cloudwatch-observability/crds to make sure the CRDs are up to date.
6. Ran helm upgrade --install amazon-cloudwatch-observability helm-charts/charts/amazon-cloudwatch-observability --values helm-charts/charts/amazon-cloudwatch-observability/values.yaml --set clusterName=cloudwatchagent-operator --set region=us-west-2 --set manager.autoInstrumentationImage.java.resources.limits.cpu=200m --set manager.autoInstrumentationImage.java.resources.limits.memory=512Mi --set manager.autoInstrumentationImage.java.resources.requests.cpu=200m --set manager.autoInstrumentationImage.java.resources.requests.memory=51Mi using the updated helm chart with the local changes.

We can confirm this works since when we run kubectl edit deployment amazon-cloudwatch-observability-controller-manager, we can see the following:

7. Ran kubectl apply -f amazon-cloudwatch-agent-operator/integration-tests/java/sample-deployment-java.yaml to deploy a sample application, which is already in the operator repo for testing.
8. Ran kubectl get pods to see the name of the sample app.
9. Ran kubectl describe pod <sample-app-pod> to see if the limits are what we configured.

The limits are correctly set.

Test cases:
helm upgrade --install amazon-cloudwatch-observability helm-charts/charts/amazon-cloudwatch-observability --values helm-charts/charts/amazon-cloudwatch-observability/values.yaml --set clusterName=cloudwatchagent-operator --set region=us-west-2 --set manager.autoInstrumentationImage.java.resources.limits.cpu=200m --set manager.autoInstrumentationImage.java.resources.limits.memory="" --set manager.autoInstrumentationImage.java.resources.requests.cpu=200m --set manager.autoInstrumentationImage.java.resources.requests.memory=51Mi

helm upgrade --install amazon-cloudwatch-observability helm-charts/charts/amazon-cloudwatch-observability --values helm-charts/charts/amazon-cloudwatch-observability/values.yaml --set clusterName=cloudwatchagent-operator --set region=us-west-2 --set manager.autoInstrumentationImage.java.resources.limits.cpu=test --set manager.autoInstrumentationImage.java.resources.limits.memory=512Mi --set manager.autoInstrumentationImage.java.resources.requests.cpu=200m --set manager.autoInstrumentationImage.java.resources.requests.memory=51Mi

Removed { to break the argument.
