Allow configuration of NGINX Plus API access (#3066)
Allow configuration of NGINX Plus API access. Problem: We want the ability to configure access to the NGINX Plus dashboard. Solution: Add a field AllowedAddresses in the NginxProxy API to allow the user to configure access to the NGINX Plus dashboard. Testing: Unit tests. Manually configured an NginxProxy resource, set up a Kind cluster with a Nodeport following our Get started guide, and confirmed that I could access the dashboard without needing to port-forward. Verified nginx plus template code is present when running on nginx plus and not present when running on nginx oss.
