Controller does not clear stale listener SSL configuration of existing Ingress changed to TCP passthrough

[jlamillan]

OCI Native Ingress Controller did not clear stale listener SSL configuration when an Ingress was changed/configured as TCP passthrough.

Steps to reproduce:

1. Create or have an OCI LB listener with SSL configured.
2. Update the Ingress using the same listener port with: oci-native-ingress.oraclecloud.com/protocol: TCP
3. Observe that the listener remains use-ssl=true instead of clearing SSL config and doing TLS passthrough to the backend.

When the listener should look like this based on the above ingress of TLS passthrough:
