[RFE] Configure `routes` to `pulp-certguard`

Is your feature request related to a problem? Please describe.
We need to verify if our configuration of OCP Routes works with pulp-certguard.
The current configuration is already doing the edge TLS termination (the Ingress Controller terminates TLS encryption before forwarding traffic to pulp-api/pulp-content), but we also need to check if it is possible to do the missing configurations from https://docs.pulpproject.org/pulp_certguard/reverse_proxy_config.html.

Describe the solution you'd like
Verify if it is possible to configure OCP Routes with the settings from https://docs.pulpproject.org/pulp_certguard/reverse_proxy_config.html and, if it is, update the operator with the expected configs.

Start by reading the linked pulp-certguard reverse proxy configuration documentation and compare its requirements with the current OCP Routes setup for pulp-api and pulp-content. Verify whether those settings can be represented by the operator, then update the operator with the expected configuration if supported. Done means the compatibility is established and the required operator configuration is documented or implemented.
