Add option for Container Insights with enhanced observability

[emeth-marco]

Is your feature request related to a problem?
There is no way to enable enhanced observability for container insights, so some dashboard don't have data to display

Is your feature request related to a specific Helm chart, if yes mention name of the chart?
Yes, aws-cloudwatch-metrics

Describe the solution you'd like
Add an option to define the following in the config map:

"enhanced_container_insights": true

Eg.
cwagentconfig.json: |
{
"logs": {
"metrics_collected": {
"kubernetes": {
"cluster_name": "{{ .Values.clusterName }}",
"enhanced_container_insights": {{ .Values.enhanced_observability_enabled }},
"metrics_collection_interval": 60
}
},

Curious if either @ivan-sukhomlyn or @emeth-marco was able to leverage this new flag? I'm not currently able to get this to work - aws/amazon-cloudwatch-agent#1030
