Remove readiness probe and health check from otel-agent sidecars

Remove the readiness probe and health check from otel-agent containers in reconciler, reconciler-manager, and resourcegroup controller to align container behavior. The healthcheck component can fail to bind to the port or respond under CPU throttling, causing unnecessary pod unready states even when the container is running. The otel-collector health check in the config-management-monitoring namespace is retained since it is tied to a Service.
