Cannot deploy multiple trino clusters in the same k8s namespace

[sudohainguyen]

Describe the bug

Not able to deploy multiple clusters using helm chart due to configmap conflicts (caused by this line for example)

chart version: 0.20.0

Suggestion

Templating configmap objects name using predefined template in _helpers.tpl e.g. instead of trino-resource-groups-volume-coordinator use trino-resource-groups-volume-{{ template "trino.coordinator" . }}
