Ability to run the master and replica load-balancers from the same host

[cowwoc]

• Which image of the operator are you using? e.g. ghcr.io/zalando/postgres-operator:v1.14.0
• Where do you run it - cloud or metal? Kubernetes or OpenShift? local k3d cluster
• Are you running Postgres Operator in production? no
• Type of issue? feature request

The master and replica load balancers both use the same port number, preventing them from running on the same host. Please provide a way to change the port number being used by each load balancer so we can run them on the same host if needed. This is especially needed for debugging/testing against a local cluster.

Alternatively, provide a way to run internal load balancers (without a hostport). I just need a way to route the application (running inside the cluster) to the master or replicate databases.
