Nginx is not used

[2tefan]

When enabling Nginx, both Nginx and Nautobot expose a port with the name http. This results in the Nginx service not being used, because the service uses the port from Nautobot.

There are two solutions I could think of:

• Changing the port name for Nautobot (bad, because this could break liveness probes and so on)
• Changing the port name for Nginx - would need change of service target port
