Add more detail to helm install commands (nginx#1299)

Problem: Some environments may not want to have a Service installed by default. Our instructions for installing via helm are not clear about this.

Solution: Update helm installation docs to be clear about how to alter the installation commands. Also cleaned up the commands/docs a bit.
