CP/DP Split: Support configuring NodePorts

[sjberman]

Problem: Now that the control plane provisions the NGINX Service, users can't set specific NodePorts values.

Solution: Allow users to specify NodePorts in the helm chart (globally) and in the NginxProxy resource.

Testing: Verified that NodePorts are configurable and accessible.

Closes #3240
