Missing ServiceAccount resources and config from upstream echo-server chart

[jrbeilke]

Found a bug? Maybe our Slack Community can help.

Describe the Bug

The upstream echo-server helm chart has a ServiceAccount helper, resource, and declaration on the container/pod, but the CP component chart only has the helper and is missing the others ie.

• https://github.com/Ealenn/charts/blob/master/charts/echo-server/templates/_helpers.tpl#L50
• https://github.com/Ealenn/charts/blob/master/charts/echo-server/templates/serviceaccount.yaml
• https://github.com/Ealenn/charts/blob/master/charts/echo-server/templates/deployment.yaml#L25

This is getting flagged in security scans (ie. Sonar) because the service account permissions cannot be restricted:

Expected Behavior

ServiceAccount resources and configuration from upstream chart are included in CP component so that service account permissions can be configured to remediate possible security issue
