Add nodePort for LoadBalancer only if allocateLoadBalancerNodePorts

[Chupaka]

Proposed changes

In v3.7.0 the chart started to set nodePort field for LoadBalancer service type in addition to NodePort type. But if we disable allocateLoadBalancerNodePorts, we don't need to set nodePorts.

Also, allocateLoadBalancerNodePorts is true by default (in k8s), not false.
