Chart 3.59.4 creates cluster-agent objects even when cluster agent is disabled

[luitzw]

Describe what happened: The chart creates configmap/-cluster-agent-confd, ClusterRole/-ksm-core, ClusterRoleBinding/-ksm-core even when clusterAgent.enabled=false is used.

Describe what you expected: Omit the create of the cluster agent resources when clusterAgent.enabled=false is used
